Benjamin Franklin

Benjamin Franklin


Benjamin Franklin (January 17, 1706 ­ April 17, 1790) was one of the Founding Fathers of the United States of America. A noted polymath, Franklin was a leading author and printer, satirist, political theorist, politician, scientist, inventor, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the Enlightenment and the history of physics for his discoveries and theories regarding electricity. He invented the lightning rod, bifocals, the Franklin stove, a carriage odometer, and the glass 'armonica'.

He formed both the first public lending library in America and first fire department in Pennsylvania. He was an early proponent of colonial unity, and as a political writer and activist he supported the idea of an American nation. As a diplomat during the American Revolution he secured the French alliance that helped to make independence of the United States possible.

Franklin is credited as being foundational to the roots of American values and character, a marriage of the practical and democratic Puritan values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of Henry Steele Commager, "In Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin, "the most accomplished American of his age and the most influential in inventing the type of society America would become."

Franklin became a newspaper editor, printer, and merchant in Philadelphia, becoming very wealthy, writing and publishing Poor Richard's Almanack and the Pennsylvania Gazette. Franklin was interested in science and technology, and gained international renown for his famous experiments. He played a major role in establishing the University of Pennsylvania and Franklin & Marshall College and was elected the first president of the American Philosophical Society.

Franklin became a national hero in America when he spearheaded the effort to have Parliament repeal the unpopular Stamp Act. An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco-American relations. From 1775 to 1776, Franklin was Postmaster General under the Continental Congress and from 1785 to 1788 was President of the Supreme Executive Council of Pennsylvania. Toward the end of his life, he became one of the most prominent abolitionists.

His colorful life and legacy of scientific and political achievement, and status as one of America's most influential Founding Fathers, has seen Franklin honored on coinage and money; warships; the names of many towns, counties, educational institutions, namesakes, and companies; and more than two centuries after his death, countless cultural references.


Ancestry

Franklin's father, Josiah Franklin, was born at Ecton, Northamptonshire, England on December 23, 1657, the son of Thomas Franklin, a blacksmith and farmer, and Jane White. His mother, Abiah Folger, was born in Nantucket, Massachusetts, on August 15, 1667, to Peter Folger, a miller and schoolteacher and his wife Mary Morrill, a former indentured servant. A descendant of the Folgers, J.A. Folger, founded Folgers Coffee in the 19th century. Josiah Franklin had seventeen children with his two wives. He married his first wife, Anne Child, in about 1677 in Ecton and emigrated with her to Boston in 1683; they had three children before emigrating, and four after. After her death, Josiah was married to Abiah Folger on July 9, 1689 in the Old South Meeting House by Samuel Willard. Benjamin, their eighth child, was Josiah Franklin's fifteenth child and tenth and last son.

Josiah Franklin converted to Puritanism in the 1670s. Puritanism was a Protestant movement in England to "purify" Anglicanism from elements of the Roman Catholic religion, which they considered superstitious. Three things were important to the Puritans: that each congregation would be self-governing, that ministers give sermons instead of performing rituals such as a Mass, and individual Bible study so that each believer could develop a personal understanding and relationship with God. Puritanism appealed to smart, middle-class people such as Benjamin Franklin's father, who enjoyed the governance meetings, discussion, study, and personal independence.

The roots of American democracy can be seen in these Puritan values of self-government, the importance of the individual and active indignation against unjust authority, which were passed on to Benjamin Franklin and other founding fathers, such as John Adams. One of Josiah's core Puritan values was that personal worth is earned through hard work, which makes the industrious man the equal of kings, which Ben Franklin etched onto his father's tombstone, from his father Josiah's favorite Bible quote, from the Hebrew Bible, Proverbs 22:29: "Seest thou a man diligent in his calling, he shall stand before Kings."

Hard work and equality were two Puritan values Ben Franklin preached throughout his own life Benjamin Franklin was born on Milk Street, in Boston, Massachusetts, on January 17, 1706 and baptized at Old South Meeting House. His father, Josiah Franklin, was a tallow chandler, a maker of candles and soap, whose second wife, Abiah Folger, was Benjamin's mother. Josiah's marriages produced 17 children; Benjamin was the fifteenth child and youngest son. Josiah wanted Ben to attend school with the clergy but only had enough money to send him to school for two years.

He attended Boston Latin School but did not graduate; he continued his education through voracious reading. Although "his parents talked of the church as a career" for Franklin, his schooling ended when he was ten. He then worked for his father for a time and at 12 he became an apprentice to his brother James, a printer, who taught Ben the printing trade. When Ben was 15, James created The New-England Courant, the first truly independent newspaper in the colonies. When denied the chance to write a letter to the paper for publication, Franklin invented the pseudonym of "Mrs. Silence Dogood," who was ostensibly a middle-aged widow. Her letters were published, and became a subject of conversation around town. Neither James nor the Courant's readers were aware of the ruse, and James was unhappy with Ben when he discovered the popular correspondent was his younger brother. Franklin left his apprenticeship without permission, and in so doing became a fugitive.

At age 17, Franklin ran away to Philadelphia, Pennsylvania, seeking a new start in a new city. When he first arrived he worked in several printer shops around town. However, he was not satisfied by the immediate prospects. After a few months, while working in a printing house, Franklin was convinced by Pennsylvania Governor Sir William Keith to go to London, ostensibly to acquire the equipment necessary for establishing another newspaper in Philadelphia. Finding Keith's promises of backing a newspaper to be empty, Franklin worked as a typesetter in a printer's shop in what is now the Church of St Bartholomew-the-Great in the Smithfield area of London. Following this, he returned to Philadelphia in 1726 with the help of a merchant named Thomas Denham, who gave Franklin a position as clerk, shopkeeper, and bookkeeper in Denham's merchant business.

In 1727, Benjamin Franklin, 21, created the Junto, a group of "like minded aspiring artisans and tradesmen who hoped to improve themselves while they improved their community." The Junto was a discussion group for issues of the day; it subsequently gave rise to many organizations in Philadelphia.

Reading was a great pastime of the Junto, but books were rare and expensive. The members created a library, and initially pooled their own books together. This did not work, however, and Franklin initiated the idea of a subscription library, where the members pooled their monetary resources to buy books. This idea was the birth of the Library Company, with the charter of the Library Company of Philadelphia created in 1731 by Franklin. Franklin hired the first American librarian in 1732, Louis Timothee. and spread widely through Poor Richard's Almanac and his autobiography.

Ben Franklin's mother, Abiah Folger, was born into a Puritan family that was among the first Pilgrims to flee to Massachusetts for religious freedom, when King Charles I of England began persecuting Protestants. They sailed for Boston in 1635. Her father was "the sort of rebel destined to transform colonial America."[6] As clerk of the court, he was jailed for disobeying the local magistrate in defense of middle-class shopkeepers and artisans in conflict with wealthy landowners. Ben Franklin followed in his grandfather's footsteps in his battles against the wealthy Penn family that owned the Pennsylvania Colony.

Early life

Benjamin Franklin was born on Milk Street, in Boston, Massachusetts, on January 17, 1706 and baptized at Old South Meeting House. His father, Josiah Franklin, was a tallow chandler, a maker of candles and soap, whose second wife, Abiah Folger, was Benjamin's mother. Josiah's marriages produced 17 children; Benjamin was the fifteenth child and youngest son.

Franklin left his apprenticeship without permission, and in so doing became a fugitive.

At age 17, Franklin ran away to Philadelphia, Pennsylvania, seeking a new start in a new city. When he first arrived he worked in several printer shops around town. However, he was not satisfied by the immediate prospects. After a few months, while working in a printing house, Franklin was convinced by Pennsylvania Governor Sir William Keith to go to London, ostensibly to acquire the equipment necessary for establishing another newspaper in Philadelphia. Finding Keith's promises of backing a newspaper to be empty, Franklin worked as a typesetter in a printer's shop in what is now the Church of St Bartholomew-the-Great in the Smithfield area of London. Following this, he returned to Philadelphia in 1726 with the help of a merchant named Thomas Denham, who gave Franklin a position as clerk, shopkeeper, and bookkeeper in Denham's merchant business.

In 1727, Benjamin Franklin, 21, created the Junto, a group of "like minded aspiring artisans and tradesmen who hoped to improve themselves while they improved their community." The Junto was a discussion group for issues of the day; it subsequently gave rise to many organizations in Philadelphia.

Reading was a great pastime of the Junto, but books were rare and expensive. The members created a library, and initially pooled their own books together. This did not work, however, and Franklin initiated the idea of a subscription library, where the members pooled their monetary resources to buy books. This idea was the birth of the Library Company, with the charter of the Library Company of Philadelphia created in 1731 by Franklin. Franklin hired the first American librarian in 1732, Louis Timothee.

Originally, the books were kept in the homes of the first librarians, but in 1739 the collection was moved to the second floor of the State House of Pennsylvania, now known as Independence Hall. In 1791, a new building was built specifically for the library. The Library Company flourished with no competition and gained many priceless collections from bibliophiles such as James Logan and his physician brother William. The Library Company is now a great scholarly and research library with 500,000 rare books, pamphlets, and broadsides, more than 160,000 manuscripts, and 75,000 graphic items.

Upon Denham's death, Franklin returned to his former trade. By 1730, Franklin had set up a printing house of his own and had contrived to become the publisher of a newspaper called The Pennsylvania Gazette. The Gazette gave Franklin a forum for agitation about a variety of local reforms and initiatives through printed essays and observations. Over time, his commentary, together with a great deal of savvy about cultivating a positive image of an industrious and intellectual young man, earned him a great deal of social respect; though even after Franklin had achieved fame as a scientist and statesman, he habitually signed his letters with the unpretentious 'B. Franklin, Printer.'

In 1731, Franklin was initiated into the local Freemason lodge, becoming a grand master in 1734, indicating his rapid rise to prominence in Pennsylvania. That same year, he edited and published the first Masonic book in the Americas, a reprint of James Anderson's Constitutions of the Free-Masons. Franklin remained a Freemason throughout the rest of his life.

Common-law marriage to Deborah Read

At the age of 17, Franklin proposed to 15-year-old Deborah Read while a boarder in the Read home. At that time, the mother was wary of allowing her young daughter to wed Franklin, who was on his way to London at Governor Sir William Keith's request, and also because of his financial instability. Her own husband having recently died, Mrs. Read declined his offer of marriage to her daughter.

While Franklin was in London, his trip was extended, and there were problems to do with Sir William's promises of support. Perhaps because of the circumstances of this delay, Deborah married a man named John Rodgers. This proved to be a regrettable decision. Rodgers shortly avoided his debts and prosecution by fleeing to Barbados with her dowry, leaving Deborah behind. With Rodgers' fate unknown, and bigamy illegal, Deborah was not free to remarry.

Franklin established a common-law marriage with Deborah Read on September 1, 1730, and besides taking in young William, together they had two children. The first, Francis Folger Franklin, born October 1732, died of smallpox in 1736. Sarah Franklin, nicknamed Sally, was born in 1743. She eventually married Richard Bache, had seven children, and cared for her father in his old age.

Deborah's fear of the sea meant that she never accompanied Franklin on any of his extended trips to Europe, despite his repeated requests. However, Franklin did not leave London to visit Deborah even after she wrote to him in November 1769 saying her illness was due to ³dissatisfied distress² because of his prolonged absence. Deborah Read Franklin died of a stroke in 1774, while Benjamin was on an extended trip to England.


Illegitimate son William

In 1730, at the age of 24, Franklin publicly acknowledged an illegitimate son named William, who would eventually become the last Loyalist governor of New Jersey. While the identity of William's mother remains unknown, perhaps the responsibility of an infant child gave Franklin a reason to take up residence with Deborah Read. William was raised in the Franklin household but eventually broke with his father over opinions regarding the treatment of the colonies by the British government. The elder Franklin could never accept William's decision to declare his loyalty to the crown. Any hope of reconcillation was shattered when William Franklin became leader of the The Board of Associated Loyalists - a quasi-military organization, headquartered in British occupied New York City, which, among other things, launched guerilla forages into New Jersey, southern Connecticut, and New York counties north of the city. In the preliminary peace talks in 1782 with Britain "...Franklin insisted that loyalists who had borne arms against the United States would be excluded from this plea (that they be given a general pardon). He was undoubtedly thinking of William Franklin.". William left New York along with the British troops. He settled in England, never to return.

Success as an author


In 1733, Franklin began to publish the famous Poor Richard's Almanack (with content both original and borrowed) under the pseudonym Richard Saunders, on which much of his popular reputation is based. Franklin frequently wrote under pseudonyms. Although it was no secret that Franklin was the author, his Richard Saunders character repeatedly denied it. "Poor Richard's Proverbs," adages from this almanac, such as "A penny saved is twopence dear" (often misquoted as "A penny saved is a penny earned"), "Fish and visitors stink in three days" remain common quotations in the modern world. Wisdom in folk society meant the ability to provide an apt adage for any occasion, and Franklin's readers became well prepared. He sold about ten thousand copies per year (a circulation equivalent to nearly three million today).

In 1758, the year in which he ceased writing for the Almanack, he printed Father Abraham's Sermon, also known as The Way to Wealth. Franklin's autobiography, published after his death, has become one of the classics of the genre.


Inventions and scientific inquiries

Franklin was a prodigious inventor. Among his many creations were the lightning rod, the glass harmonica, the Franklin stove, bifocal glasses, and the flexible urinary catheter. Franklin never patented his inventions; in his autobiography he wrote, "... as we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously."

His inventions also included social innovations, such as paying forward. Franklin's fascination with innovation could be viewed as altruistic; he wrote that his scientific works were to be used for increasing efficiency and human improvement. One such improvement was his effort to expedite news services through his printing presses.

As deputy postmaster, Franklin became interested in the North Atlantic Ocean circulation patterns.

In 1768 Franklin visited England as postmaster general and there he heard a curious complaint by Colonial board of Customs: Why did it take British mail ships which were called packets a couple of weeks longer to reach New York from England than it took an average merchant ship to reach Newport, Rhode Island despite merchants ships leaving London having to sail down Thames and then the length of the English channel before they sailed across Atlantic, while the packets left from Falmouth in Cornwall right on the ocean's doorstep.

Intrigued, Franklin invited his cousin Timothy Folger, an experienced Nantucket whaler captain, who happened to be in London at that time, for dinner. Folger told him that Merchant ships routinely avoided Gulf stream while the mail packet captains sailed dead into its foul easterly set despite American whalers telling them that they were stemming a current to the value of three miles an hour. Franklin worked with Folger and other experienced ship captains, learning enough to chart the Gulf Stream, giving it the name by which it's still known today. It took many years for British sea captains to follow Franklin's advice on navigating the current, but once they did, they were able to gain two weeks in sailing time.

Franklin's Gulf Stream chart got published in 1770, in England where it was completely ignored. Subsequent versions were printed in France in 1778 and the United states in 1786. The British edition of the chart which was the original was so thoroughly ignored that everyone assumed it was lost forever until, Phil Richardson, a Woods Hole Oceanographer and Gulf Stream expert discovered it in Bibliothèque Nationale in Paris. This got front page coverage in the New York Times.

In 1743, Franklin founded the American Philosophical Society to help scientific men discuss their discoveries and theories. He began the electrical research that, along with other scientific inquiries, would occupy him for the rest of his life, in between bouts of politics and moneymaking.

In 1748, he retired from printing and went into other businesses. He created a partnership with his foreman, David Hall, which provided Franklin with half of the shop's profits for 18 years. This lucrative business arrangement provided leisure time for study, and in a few years he had made discoveries that gave him a reputation with the educated throughout Europe and especially in France.

His discoveries included his investigations of electricity. Franklin proposed that "vitreous" and "resinous" electricity were not different types of "electrical fluid" (as electricity was called then), but the same electrical fluid under different pressures. He was the first to label them as positive and negative respectively, and he was the first to discover the principle of conservation of charge.

In 1750, he published a proposal for an experiment to prove that lightning is electricity by flying a kite in a storm that appeared capable of becoming a lightning storm. On May 10, 1752, Thomas-François Dalibard of France conducted Franklin's experiment (using a 40-foot (12 m)-tall iron rod instead of a kite) and extracted electrical sparks from a cloud. On June 15, Franklin may have possibly conducted his famous kite experiment in Philadelphia and also successfully extracted sparks from a cloud, although there are theories that suggest he never performed the experiment. Franklin's experiment was not written up until Joseph Priestley's 1767 History and Present Status of Electricity; the evidence shows that Franklin was insulated (not in a conducting path, since he would have been in danger of electrocution in the event of a lightning strike).

Others, such as Prof. Georg Wilhelm Richmann of Saint Petersburg, Russia, were electrocuted during the months following Franklin's experiment. In his writings, Franklin indicates that he was aware of the dangers and offered alternative ways to demonstrate that lightning was electrical, as shown by his use of the concept of electrical ground. If Franklin did perform this experiment, he did not do it in the way that is often described, flying the kite and waiting to be struck by lightning, as it would have been fatal. Instead, he used the kite to collect some electric charge from a storm cloud, which implied that lightning was electrical.

Franklin's electrical experiments led to his invention of the lightning rod. He noted that conductors with a sharp rather than a smooth point were capable of discharging silently, and at a far greater distance. He surmised that this knowledge could be of use in protecting buildings from lightning, by attaching "upright Rods of Iron, made sharp as a Needle and gilt to prevent Rusting, and from the Foot of those Rods a Wire down the outside of the Building into the Ground;...Would not these pointed Rods probably draw the Electrical Fire silently out of a Cloud before it came nigh enough to strike, and thereby secure us from that most sudden and terrible Mischief!" Following a series of experiments on Franklin's own house, lightning rods were installed on the Academy of Philadelphia (later the University of Pennsylvania) and the Pennsylvania State House (later Independence Hall) in 1752.

In recognition of his work with electricity, Franklin received the Royal Society's Copley Medal in 1753, and in 1756 he became one of the few eighteenth century Americans to be elected as a Fellow of the Society. The cgs unit of electric charge has been named after him: one franklin (Fr) is equal to one statcoulomb.

On October 21, 1743, according to popular myth, a storm moving from the southwest denied Franklin the opportunity of witnessing a lunar eclipse. Franklin was said to have noted that the prevailing winds were actually from the northeast, contrary to what he had expected. In correspondence with his brother, Franklin learned that the same storm had not reached Boston until after the eclipse, despite the fact that Boston is to the northeast of Philadelphia. He deduced that storms do not always travel in the direction of the prevailing wind, a concept which would have great influence in meteorology.

Franklin noted a principle of refrigeration by observing that on a very hot day, he stayed cooler in a wet shirt in a breeze than he did in a dry one. To understand this phenomenon more clearly Franklin conducted experiments.

On one warm day in Cambridge, England, in 1758, Franklin and fellow scientist John Hadley experimented by continually wetting the ball of a mercury thermometer with ether and using bellows to evaporate the ether. With each subsequent evaporation, the thermometer read a lower temperature, eventually reaching 7°F (-14°C). Another thermometer showed the room temperature to be constant at 65°F (18°C). In his letter "Cooling by Evaporation," Franklin noted that "one may see the possibility of freezing a man to death on a warm summer¹s day."

An aging Franklin accumulated all his Oceanographic findings in Maritime Observations, published by the Philosophical Society's transactions in 1786.[citation needed] It contained ideas for sea anchors, catamaran hulls, watertight compartments, shipboard lighting rods, and a soup bowl designed to stay stable in stormy weather! There is also a story, perhaps apocryphal, that during the American War of Independence Franklin toyed around with the idea of using the Atlantic Gulf Stream as a weapon if somehow it could be deflected, as with a dike, England could be plunged into a new ice age.


Musical Endeavors

Franklin is known to have played the violin, the harp, and the guitar. He also composed music, notably a string quartet in early classical style, and invented a much-improved version of the glass harmonica, in which each glass was made to rotate on its own, with the player's fingers held steady, instead of the other way around; this version soon found its way to Europe.


Chess

Franklin was an avid chess player. The first chess writing in America was his "Morals of Chess" in Columbian Magazine, December 1786. This essay in praise of chess and prescribing a code of behavior for it has been widely reprinted and translated. He and a friend also used chess as a means of learning the Italian language, which both were studying; the winner of each game between them had the right to assign a task, such as parts of the Italian grammar to be learned by heart, to be performed by the loser before their next meeting. Franklin was inducted into the US Chess Hall of Fame in 1999.


Public Life

In 1736, Franklin created the Union Fire Company, one of the first volunteer firefighting companies in America. In the same year, he printed a new currency for New Jersey based on innovative anti-counterfeiting techniques which he had devised. Throughout his career, Franklin was an advocate for paper money, publishing A Modest Enquiry into the Nature and Necessity of a Paper Currency in 1729, and his printer printed money. He was influential in the more restrained and thus successful monetary experiments in the Middle Colonies, which stopped deflation without causing excessive inflation. In 1766 he made a case for paper money to the British House of Commons.

As he matured, Franklin began to concern himself more with public affairs. In 1743, he set forth a scheme for The Academy and College of Philadelphia. He was appointed president of the academy in November 13, 1749, and it opened on August 13, 1751. At its first commencement, on May 17, 1757, seven men graduated; six with a Bachelor of Arts and one as Master of Arts. It was later merged with the University of the State of Pennsylvania to become the University of Pennsylvania.

In 1753, both Harvard and Yale awarded him honorary degrees.

In 1751, Franklin and Dr. Thomas Bond obtained a charter from the Pennsylvania legislature to establish a hospital. Pennsylvania Hospital was the first hospital in what was to become the United States of America.

Franklin became involved in Philadelphia politics and rapidly progressed. In October 1748, he was selected as a councilman, in June 1749 he became a Justice of the Peace for Philadelphia, and in 1751 he was elected to the Pennsylvania Assembly. On August 10, 1753, Franklin was appointed joint deputy postmaster-general of North America. His most notable service in domestic politics was his reform of the postal system, but his fame as a statesman rests chiefly on his subsequent diplomatic services in connection with the relations of the colonies with Great Britain, and later with France.

In 1754, he headed the Pennsylvania delegation to the Albany Congress. This meeting of several colonies had been requested by the Board of Trade in England to improve relations with the Indians and defense against the French. Franklin proposed a broad Plan of Union for the colonies. While the plan was not adopted, elements of it found their way into the Articles of Confederation and the Constitution.

In 1756, Franklin organized the Pennsylvania Militia. He used Tun Tavern as a gathering place to recruit a regiment of soldiers to go into battle against the Native American uprisings that beset the American colonies. Reportedly Franklin was elected "Colonel" of the Associated Regiment but declined the honor.

In 1757, he was sent to England by the Pennsylvania Assembly as a colonial agent to protest against the political influence of the Penn family, the proprietors of the colony. He remained there for five years, striving to end the proprietors' prerogative to overturn legislation from the elected Assembly, and their exemption from paying taxes on their land. His lack of influential allies in Whitehall led to the failure of this mission.

In 1759, the University of St Andrews awarded him an Honorary Doctor of Laws degree. In 1762, Oxford University awarded Franklin an honorary doctorate for his scientific accomplishments and from then on he went by "Doctor Franklin." He also managed to secure a post for his illegitimate son, William Franklin, as Colonial Governor of New Jersey.

During his stay in London, Franklin became involved in radical politics. He was a member of the Club of Honest Whigs, alongside thinkers such as Richard Price.

In 1756, Franklin became a member of the Society for the Encouragement of Arts, Manufactures & Commerce (now Royal Society of Arts or RSA, which had been founded in 1754), whose early meetings took place in coffee shops in London's Covent Garden district, close to Franklin's main residence in Craven Street (the only one of his residences to survive and which opened to the public as the Benjamin Franklin House museum on January 17, 2006). After his return to America, Franklin became the Society's Corresponding Member and remained closely connected with the Society. The RSA instituted a Benjamin Franklin Medal in 1956 to commemorate the 250th anniversary of Franklin's birth and the 200th anniversary of his membership of the RSA.

During his stays at Craven Street in London between 1757 and 1775, Franklin developed a close friendship with his landlady, Margaret Stevenson and her circle of friends and relations, in particular her daughter Mary, who was more often known as Polly.

In 1759, he visited Edinburgh with his son, and recalled his conversations there as "the densest happiness of my life."

He also joined the influential Birmingham based Lunar Society with whom he regularly corresponded and on occasion, visited in Birmingham in the West Midlands.


Coming of Revolution

In 1763, soon after Franklin returned to Pennsylvania, the western frontier was engulfed in a bitter war known as Pontiac's Rebellion. The Paxton Boys, a group of settlers convinced that the Pennsylvania government was not doing enough to protect them from American Indian raids, murdered a group of peaceful Susquehannock Indians and then marched on Philadelphia. Franklin helped to organize the local militia in order to defend the capital against the mob, and then met with the Paxton leaders and persuaded them to disperse. Franklin wrote a scathing attack against the racial prejudice of the Paxton Boys. "If an Indian injures me," he asked, "does it follow that I may revenge that Injury on all Indians?"

At this time, many members of the Pennsylvania Assembly were feuding with William Penn's heirs, who controlled the colony as proprietors. Franklin led the "anti-proprietary party" in the struggle against the Penn family, and was elected Speaker of the Pennsylvania House in May 1764. His call for a change from proprietary to royal government was a rare political miscalculation, however: Pennsylvanians worried that such a move would endanger their political and religious freedoms. Because of these fears, and because of political attacks on his character, Franklin lost his seat in the October 1764 Assembly elections. The anti-proprietary party dispatched Franklin to England to continue the struggle against the Penn family proprietorship, but during this visit, events would drastically change the nature of his mission.

In London, Franklin opposed the 1765 Stamp Act, but when he was unable to prevent its passage, he made another political miscalculation and recommended a friend to the post of stamp distributor for Pennsylvania. Pennsylvanians were outraged, believing that he had supported the measure all along, and threatened to destroy his home in Philadelphia. Franklin soon learned of the extent of colonial resistance to the Stamp Act, and his testimony before the House of Commons led to its repeal. With this, Franklin suddenly emerged as the leading spokesman for American interests in England. He wrote popular essays on behalf of the colonies, and Georgia, New Jersey, and Massachusetts also appointed him as their agent to the Crown.

In September 1767, Franklin visited Paris with his usual traveling partner, Sir John Pringle. News of his electrical discoveries was widespread in France. His reputation meant that he was introduced to many influential scientists and politicians, and also to King Louis XV.

While living in London in 1768, he developed a phonetic alphabet in A Scheme for a new Alphabet and a Reformed Mode of Spelling. This reformed alphabet discarded six letters Franklin regarded as redundant (c, j, q, w, x, and y), and substituted six new letters for sounds he felt lacked letters of their own. His new alphabet, however, never caught on and he eventually lost interest.

In 1771, Franklin traveled extensively around the British Isles staying with, among others, Joseph Priestley and David Hume. In Dublin, Franklin was invited to sit with the members of the Irish Parliament rather than in the gallery. He was the first American to be given this honor.

While touring Ireland, he was moved by the level of poverty he saw. Ireland's economy was affected by the same trade regulations and laws of Britain which governed America. Franklin feared that America could suffer the same effects should Britain¹s "colonial exploitation" continue.

In 1773, Franklin published two of his most celebrated pro-American satirical essays: Rules by Which a Great Empire May Be Reduced to a Small One, and An Edict by the King of Prussia.

He also published an Abridgment of the Book of Common Prayer, anonymously with Francis Dashwood. Among the unusual features of this work is a funeral service reduced to six minutes in length, "to preserve the health and lives of the living."


Hutchinson Letters

Franklin obtained private letters of Massachusetts governor Thomas Hutchinson and lieutenant governor Andrew Oliver which proved they were encouraging London to crack down on the rights of the Bostonians. Franklin sent them to America where they escalated the tensions. Franklin now appeared to the British as the fomenter of serious trouble. Hopes for a peaceful solution ended as he was systematically ridiculed and humiliated by the Privy Council. He left London in March, 1775.


Declaration of Independence

By the time Franklin arrived in Philadelphia on May 5, 1775, the American Revolution had begun with fighting at Lexington and Concord. The New England militia had trapped the main British army in Boston. The Pennsylvania Assembly unanimously chose Franklin as their delegate to the Second Continental Congress. In June, 1776, he was appointed a member of the Committee of Five that drafted the Declaration of Independence. Although he was temporarily disabled by gout and unable to attend most meetings of the Committee, Franklin made several small changes to the draft sent to him by Thomas Jefferson.

At the signing, he is quoted as having replied to a comment by Hancock that they must all hang together: "Yes, we must, indeed, all hang together, or most assuredly we shall all hang separately."


Ambassador to France: 1776­1785

In December, 1776, Franklin was dispatched to France as commissioner for the United States. He lived in a home in the Parisian suburb of Passy, donated by Jacques-Donatien Le Ray de Chaumont who supported the United States. Franklin remained in France until 1785. He conducted the affairs of his country towards the French nation with great success, which included securing a critical military alliance in 1778 and negotiating the Treaty of Paris (1783).

During his stay in France, Benjamin Franklin as a freemason was Grand Master of the Lodge Les Neuf S¦urs from 1779 until 1781. His number was 24 in the Lodge. He was also a Past Grand Master of Pennsylvania. In 1784, when Franz Mesmer began to publicize his theory of "animal magnetism", which was considered offensive by many, Louis XVI appointed a commission to investigate it. These included the chemist Antoine Lavoisier, the physician Joseph-Ignace Guillotin, the astronomer Jean Sylvain Bailly, and Benjamin Franklin.


Constitutional Convention

When he finally returned home in 1785, Franklin occupied a position only second to that of George Washington as the champion of American independence. Le Ray honored him with a commissioned portrait painted by Joseph Duplessis that now hangs in the National Portrait Gallery of the Smithsonian Institution in Washington, D.C. After his return, Franklin became an abolitionist, freeing both of his slaves. He eventually became president of the Pennsylvania Abolition Society.

In 1787, Franklin served as a delegate to the Philadelphia Convention. He held an honorific position and seldom engaged in debate. He is the only Founding Father who is a signatory of all four of the major documents of the founding of the United States: the Declaration of Independence, the Treaty of Paris, the Treaty of Alliance with France, and the United States Constitution.

In 1787, a group of prominent ministers in Lancaster, Pennsylvania, proposed the foundation of a new college to be named in Franklin's honor. Franklin donated £200 towards the development of Franklin College, which is now called Franklin & Marshall College.

Between 1771 and 1788, he finished his autobiography. While it was at first addressed to his son, it was later completed for the benefit of mankind at the request of a friend.

In his later years, as Congress was forced to deal with the issue of slavery, Franklin wrote several essays that attempted to convince his readers of the importance of the abolition of slavery and of the integration of Africans into American society.

In 1790, Quakers from New York and Pennsylvania presented their petition for abolition. Their argument against slavery was backed by the Pennsylvania Abolitionist Society and its president, Benjamin Franklin.


President of Pennsylvania

Special balloting conducted October 18, 1785 unanimously elected Franklin the sixth President of the Supreme Executive Council of Pennsylvania, replacing John Dickinson. The office of President of Pennsylvania was analogous to the modern position of Governor. It is not clear why Dickinson needed to be replaced with less than two weeks remaining before the regular election. Franklin held that office for slightly over three years, longer than any other, and served the Constitutional limit of three full terms. Shortly after his initial election he was reelected to a full term on October 29, 1785, and again in the fall of 1786 and on October 31, 1787. Officially, his term concluded on November 5, 1788, but there is some question regarding the de facto end of his term, suggesting that the aging Franklin may not have been actively involved in the day-to-day operation of the Council toward the end of his time in office.


Virtue, religion, and personal beliefs

Like the other advocates of republicanism, Franklin emphasized that the new republic could survive only if the people were virtuous in the sense of attention to civic duty and rejected corruption. All his life he explored the role of civic and personal virtue, as expressed in Poor Richard's aphorisms.

Franklin had been baptized and educated in a Presbyterian Church based on the doctrines of John Calvin. Franklin's wife, Deborah, retained a life-long association with Christ Church, Philadelphia. Franklin later in life rarely attended Sunday services but commented that "...Sunday being my studying day, I never was without some religious principles. I never doubted, for instance, the existence of the Deity; that He made the world, and governed it by His providence; that the most acceptable service of God was the doing good to man; that our souls are immortal; and that all crime will be punished, and virtue rewarded, either here or hereafter."

One of Franklin's endearing beliefs was in the respect and tolerance of all religious groups. Referring to his experience in Philadelphia, he wrote in his autobiography, "new Places of worship were continually wanted, and generally erected by voluntary Contribution, my Mite for such purpose, whatever might be the Sect, was never refused."

Although Franklin's parents had intended for him to have a career in the church, Franklin became disillusioned with organized religion after discovering Deism. "I soon became a thorough Deist." He went on to attack Christian principles of free will and morality in a 1725 pamphlet, A Dissertation on Liberty and Necessity, Pleasure and Pain. He consistently attacked religious dogma, arguing that morality depended more on virtue and benevolent actions than on strict obedience to religious orthodoxy: "I think opinions should be judged by their influences and effects; and if a man holds none that tend to make him less virtuous or more vicious, it may be concluded that he holds none that are dangerous, which I hope is the case with me."

Like most Enlightenment intellectuals, Franklin separated virtue, morality, and faith from organized religion, although he felt that if religion in general grew weaker, morality, virtue, and society in general would also decline. Thus he wrote Thomas Paine, "If men are so wicked with religion, what would they be if without it."

According to David Morgan, Franklin was a proponent of all religions. He prayed to "Powerful Goodness" and referred to God as "the infinite". John Adams noted that Franklin was a mirror in which people saw their own religion: "The Catholics thought him almost a Catholic. The Church of England claimed him as one of them. The Presbyterians thought him half a Presbyterian, and the Friends believed him a wet Quaker." Whatever else Franklin was, concludes Morgan, "he was a true champion of generic religion." Ben Franklin was noted to be "the spirit of the Enlightenment."

Walter Isaacson argues that Franklin became uncomfortable with an unenhanced version of Deism and came up with his own conception of the Creator. Franklin outlined his concept of deity in 1728, in his Articles of Belief and Acts of Religion.

From this, Isaacson compares Franklin's conception of deity to that of strict Deists and orthodox Christians. He concludes that unlike most pure Deists, Franklin believed that a faith in God should inform our daily actions, but that, like other Deists, his faith was devoid of sectarian dogma. Isaacson also discusses Franklin's conception that God had created beings who do interfere in worldly matters, a point that has led some commentators, most notably A. Owen Aldridge, to read Franklin as embracing some sort of polytheism, with a bevy of lesser gods overseeing various realms and planets.

On July 4, 1776, Congress appointed a committee that included Franklin, Thomas Jefferson, and John Adams to design the Great Seal of the United States. Each member of the committee proposed a unique design: Franklin's proposal featured a design with the motto: "Rebellion to Tyrants is Obedience to God." This design was to portray a scene from the Book of Exodus, complete with Moses, the Israelites, the pillar of fire, and George III depicted as Pharaoh.

Franklin may have financially supported one particular Presbyterian group in Philadelphia.[56] According to the epitaph Franklin wrote for himself at age 20, it is clear that he believed in a physical resurrection of the body some time after death. Franklin's actual grave, however, as he specified in his final will, simply reads "Benjamin and Deborah Franklin."

Franklin's writings on virtue became the subject of much derision to some European authors, such as Jackob Fugger in his critical work Portrait of American Culture. Max Weber considered Franklin's ethical writings a culmination of the Protestant ethic, which ethic created the social conditions necessary for the birth of capitalism.


Death and legacy

Franklin died on April 17, 1790, at age 84. His funeral was attended by approximately 20,000 people. He was interred in Christ Church Burial Ground in Philadelphia. In 1728, aged 22, Franklin wrote what he hoped would be his own epitaph:

    The Body of B. Franklin Printer; Like the Cover of an old Book, Its Contents torn out, And stript of its Lettering and Gilding, Lies here, Food for Worms. But the Work shall not be wholly lost: For it will, as he believ'd, appear once more, In a new & more perfect Edition, Corrected and Amended By the Author.

Franklin's actual grave, however, as he specified in his final will, simply reads "Benjamin and Deborah Franklin."

In 1773, when Franklin's work had moved from printing to science and politics, he corresponded with a French scientist on the subject of preserving the dead for later revival by more advanced scientific methods, writing:

I should prefer to an ordinary death, being immersed with a few friends in a cask of Madeira, until that time, then to be recalled to life by the solar warmth of my dear country! But in all probability, we live in a century too little advanced, and too near the infancy of science, to see such an art brought in our time to its perfection.

Franklin bequeathed £1,000 (about $4,400 at the time) each to the cities of Boston and Philadelphia, in trust to gather interest for 200 years. The trust began in 1785 when a French mathematician named Charles-Joseph Mathon de la Cour wrote a parody of Franklin's "Poor Richard's Almanack" called "Fortunate Richard."

Mocking the unbearable spirit of American optimism represented by Franklin, the Frenchman wrote that Fortunate Richard left a small sum of money in his will to be used only after it had collected interest for 500 years. Franklin, who was 79 years old at the time, wrote to the Frenchman, thanking him for a great idea and telling him that he had decided to leave a bequest of 1,000 pounds each to his native Boston and his adopted Philadelphia.

As of 1990, more than $2,000,000 had accumulated in Franklin's Philadelphia trust, which had loaned the money to local residents. From 1940 to 1990, the money was used mostly for mortgage loans. When the trust came due, Philadelphia decided to spend it on scholarships for local high school students. Franklin's Boston trust fund accumulated almost $5,000,000 during that same time, and was used to establish a trade school that became the Franklin Institute of Boston.

A signer of both the Declaration of Independence and the Constitution, Franklin is considered one of the Founding Fathers of the U.S. His pervasive influence in the early history of the United States has led to his being jocularly called "the only President of the United States who was never President of the United States."

Franklin's likeness is ubiquitous. Since 1928, it has adorned American $100 bills, which are sometimes referred to in slang as "Benjamins" or "Franklins." From 1948 to 1964, Franklin's portrait was on the half dollar. He has appeared on a $50 bill and on several varieties of the $100 bill from 1914 and 1918. Franklin appears on the $1,000 Series EE Savings bond.

The city of Philadelphia contains around 5,000 likenesses of Benjamin Franklin, about half of which are located on the University of Pennsylvania campus. Philadelphia's Benjamin Franklin Parkway (a major thoroughfare) and Benjamin Franklin Bridge (the first major bridge to connect Philadelphia with New Jersey) are named in his honor.

In 1976, as part of a bicentennial celebration, Congress dedicated a 20-foot (6 m) marble statue in Philadelphia's Franklin Institute as the Benjamin Franklin National Memorial. Many of Franklin's personal possessions are also on display at the Institute, one of the few national memorials located on private property.

Franklin, in his "Poor Richard" persona, helped create popular culture in America. In turn he has been included in many different popular culture media, of which this list is a small, recent sample.

Daylight saving time (DST) is often erroneously attributed to a 1784 satire that Franklin published anonymously. Modern DST was first proposed by William Willett in 1907. The ancient Romans adjusted their clocks in a different way, by lengthening summer daylight hours.

Albert Einstein

Albert Einstein

March 14, 1879 - April 18, 1955
Physicist and Mathematician
Nobel Laureate for Physics 1921

"There are only two ways to live your life.
One is as though nothing is a miracle.
The other is as if everything is."
- Albert Einstein -

Albert Einstein was a German-born theoretical physicist who is widely considered one of the greatest physicists of all time.

While best known for the theory of relativity (and specifically mass-energy equivalence, E=mc2), he was awarded the 1921 Nobel Prize in Physics for his 1905 (Annus Mirabilis) explanation of the photoelectric effect and "for his services to Theoretical Physics". In popular culture, the name "Einstein" has become synonymous with great intelligence and genius. Einstein was named Time magazine's "Man of the Century."

He was known for many scientific investigations, among which were: his special theory of relativity which stemmed from an attempt to reconcile the laws of mechanics with the laws of the electromagnetic field, his general theory of relativity which extended the principle of relativity to include gravitation, relativistic cosmology, capillary action, critical opalescence, classical problems of statistical mechanics and problems in which they were merged with quantum theory, leading to an explanation of the Brownian movement of molecules; atomic transition probabilities, the probabilistic interpretation of quantum theory, the quantum theory of a monatomic gas, the thermal properties of light with a low radiation density which laid the foundation of the photon theory of light, the theory of radiation, including stimulated emission; the construction of a unified field theory, and the geometrization of physics.

Einstein was born on March 14, 1879, to a Jewish family, in Ulm, Württemberg, Germany. His father was Hermann Einstein, a salesman who later ran an electrochemical works, and his mother was Pauline née Koch. They were married in Stuttgart-Bad Cannstatt.

At his birth, Albert's mother was reputedly frightened that her infant's head was so large and oddly shaped. Though the size of his head appeared to be less remarkable as he grew older, it's evident from photographs of Einstein that his head was disproportionately large for his body throughout his life, a trait regarded as "benign macrocephaly" in large-headed individuals with no related disease or cognitive deficits. His parents also worried about his intellectual development as a child due to his initial language delay and his lack of fluency until the age of nine, though he was one of the top students in his elementary school.

In 1880, shortly after Einstein's birth the family moved to Munich, where his father and his uncle founded a company manufacturing electrical equipment (Elektrotechnische Fabrik J. Einstein & Cie). This company provided the first lighting for the Oktoberfest as well as some cabling in the suburb of Schwabing.

Albert's family members were all non-observant Jews and he attended a Catholic elementary school. At the insistence of his mother, he was given violin lessons. Though he initially disliked the lessons, and eventually discontinued them, he would later take great solace in Mozart's violin sonatas.

When Einstein was five, his father showed him a small pocket compass, and Einstein realized that something in "empty" space acted upon the needle; he would later describe the experience as one of the most revelatory events of his life. He built models and mechanical devices for fun and showed great mathematical ability early on.

In 1889, a medical student named Max Talmud (later: Talmey), who regularly visited the Einsteins, introduced Einstein to key science and philosophy texts, including Kant's Critique of Pure Reason.

Einstein attended the Luitpold Gymnasium, where he received a relatively progressive education. In 1891, he taught himself Euclidean geometry from a school booklet and began to study calculus; Einstein realized the power of deductive reasoning from Euclid's Elements, which Einstein called the "holy little geometry book" (given by Max Talmud). At school, Einstein clashed with authority and resented the school regimen, believing that the spirit of learning and creative thought were lost in such endeavors as strict rote learning.

From 1894, following the failure of Hermann Einstein's electrochemical business, the Einsteins moved to Milan and proceeded to Pavia after a few months. Einstein's first scientific work, called "The Investigation of the State of Aether in Magnetic Fields", was written contemporaneously for one of his uncles. Albert remained in Munich to finish his schooling, but only completed one term before leaving the gymnasium in the spring of 1895 to join his family in Pavia. He quit a year and a half before the final examinations, convincing the school to let him go with a medical note from a friendly doctor, but this meant that he had no secondary-school certificate. That same year, at age 16, he performed a famous thought experiment by trying to visualize what it would be like to ride alongside a light beam. He realized that, according to Maxwell's equations, light waves would obey the principle of relativity: the speed of the light would always be constant, no matter what the velocity of the observer. This conclusion would later become one of the two postulates of special relativity.

Rather than pursuing electrical engineering as his father intended for him, he followed the advice of a family friend and applied at the Federal Polytechnic Institute in Zurich in 1895. Without a school certificate he had to take an admission exam, which he - at the age of 16 being the youngest participant ­ did not pass. He had preferred travelling in northern Italy over the required preparations for the exam. Still, he easily passed the science part, but failed in general knowledge.

After that he was sent to Aarau, Switzerland to finish secondary school. He lodged with Professor Jost Winteler's family and became enamoured with Sofia Marie-Jeanne Amanda Winteler, commonly referred to as Sofie or Marie, their daughter and his first sweetheart. Einstein's sister, Maja, who was perhaps his closest confidant, was to later marry their son, Paul. While there, he studied Maxwell's electromagnetic theory and received his diploma in September 1896. Einstein subsequently enrolled at the Federal Polytechnic Institute in October and moved to Zurich, while Marie moved to Olsberg, Switzerland for a teaching post. The same year, he renounced his Württemberg citizenship to avoid military service.

In the spring of 1896, Mileva Maric started as a medical student at the University of Zurich, but after a term switched to the Federal Polytechnic Institute. She was the only woman to study in that year for the same diploma as Einstein. Maric's relationship with Einstein developed into romance over the next few years, though his mother objected because she was too old, not Jewish, and physically defective.

In 1900, Einstein was granted a teaching diploma by the Federal Polytechnic Institute. Einstein then submitted his first paper to be published, on the capillary forces of a straw, titled "Consequences of the observations of capillarity phenomena". In this paper his quest for a unified physical law becomes apparent, which he followed throughout his life. Through his friend Michele Besso, Einstein was presented with the works of Ernst Mach, and would later consider him "the best sounding board in Europe" for physical ideas. Einstein and Maric had a daughter, Lieserl Einstein, born in January 1902. Her fate is unknown; some believe she died in infancy, while others believe she was given out for adoption.

Works and Doctorate

Einstein could not find a teaching post upon graduation, mostly because his brashness as a young man had apparently irritated most of his professors. The father of a classmate helped him obtain employment as a technical assistant examiner at the Swiss Patent Office[8] in 1902. His main responsibility was to evaluate patent applications relating to electromagnetic devices. He also learned how to discern the essence of applications despite sometimes poor descriptions, and was taught by the director how "to express [him]self correctly". He occasionally corrected their design errors while evaluating the practicality of their work.

His friend from Zurich, Michele Besso, also moved to Bern and took a job at the patent office, and he became an important sounding board. Einstein also joined with two friends he made in Bern, Maurice Solovine and Conrad Habicht, to create a weekly discussion club on science and philosophy, which they grandly and jokingly named "The Olympia Academy." Their readings included Poincare, Mach, Hume, and others who influenced the development of the special theory of relativity.

Einstein married Mileva Maric on January 6, 1903. Einstein's marriage to Maric who was a mathematician, was both a personal and intellectual partnership: Einstein referred to Mileva as "a creature who is my equal and who is as strong and independent as I am". Ronald W. Clark, a biographer of Einstein, claimed that Einstein depended on the distance that existed in his marriage to Mileva in order to have the solitude necessary to accomplish his work; he required intellectual isolation. In an obituary of Einstein Abram Joffe wrote: "The author of [the papers of 1905] wasŠ a bureaucrat at the Patent Office in Bern, Einstein-Maric which has been taken as evidence of a collaborative relationship. However, most probably Joffe referred to Einstein- Maric ecause he believed that it was a Swiss custom at the time to append the spouse's surname to the husband's name. The extent of her influence on Einstein's work is a controversial and debated question.

In 1903, Einstein's position at the Swiss Patent Office had been made permanent, though he was passed over for promotion until he had "fully mastered machine technology". He obtained his doctorate under Alfred Kleiner at the University of Zürich after submitting his thesis "A new determination of molecular dimensions" ("Eine neue Bestimmung der Moleküldimensionen") in 1905.

During 1905, in his spare time, he wrote four articles that participated in the foundation of modern physics, without much scientific literature he could refer to or many fellow scientists with whom he could discuss the theories. Most physicists agree that three of those papers (on Brownian motion, the photoelectric effect, and special relativity) deserved Nobel Prizes. Only the paper on the photoelectric effect would be mentioned by the Nobel committee in the award; at the time of the award, it had the most unchallenged experimental evidence behind it, although the Nobel committee expressed the opinion that Einstein's other work would be confirmed in due course.

Some might regard the award for the photoelectric effect ironic, not only because Einstein is far better-known for relativity, but also because the photoelectric effect is a quantum phenomenon, and Einstein became somewhat disenchanted with the path quantum theory would take.

Einstein submitted this series of papers to the "Annalen der Physik". They are commonly referred to as the "Annus Mirabilis Papers" (from Annus mirabilis, Latin for 'year of wonders').

Diary Details Einstein's Final Years MSNBC - April 2004

    In the last years of Albert Einstein's life, he amused himself by telling jokes to his parrot, and avoided visitors by feigning illness, according to a newly discovered diary written by the woman known around Princeton as his last girlfriend. While Einstein also talked about the travails of his continuing work in physics, most of Johanna Fantova's diary recalls his views on world politics and his personal life. The writings are an unvarnished portrait of Einstein struggling bravely with the manifold inconveniences of sickness and old age, Freeman Dyson, a mathematician at the Institute for Advanced Study in Princeton, told The New York Times in Saturday¹s editions.

    The 62-page diary, written in German, was discovered in February in Fantova¹s personnel files at Princeton University¹s Firestone Library, where she had worked as a curator. The manuscript is the subject of an article to be published next month in The Princeton University Library Journal. According to the article, the new manuscript is the only one kept by someone close to Einstein in the final years of his life.

    "There is surprisingly little about physics in the diary," Donald Skemer, Firestone Library¹s curator of manuscripts, told The Times of Trenton. Fantova wrote that she recorded her time with the renowned physicist to "cast some additional light on our understanding of Einstein, not on the great man who became a legend in his lifetime, not on Einstein the renowned scientist, but on Einstein the humanitarian." Fantova was 22 years younger than Einstein. Although the two spent considerable time together starting in the 1940s, her journal only records their relationship from October 1953 until his death in April 1955 at age 76. She died in 1981 at age 80.

    Princeton already had a collection of the poems, letters and photos Einstein sent to Fantova, who sold them after his death to Gillett G. Griffin, a retired curator at Princeton¹s Art Museum. He gave those documents to the library. Griffin, invited many times to Einstein¹s home for dinner, said Fantova was a fixture there. "Reading what she left gives me an immediate connection with my own experience and gives everyone the immediacy of knowing Einstein himself," Griffin said.

    The diary recounts Einstein speaking about the politics of the day and portrays him as critical of speeches of Adlai Stevenson, the nuclear arms race and the anti-communist attack on the scientist J. Robert Oppenheimer by Sen. Joseph McCarthy. "This political persecution of his associate was a source of bitter disillusionment," Fantova wrote. Besides his politics, Fantova wrote of Einstein's popularity and how he tried to write back to strangers, some of whom tried to convert him to Christianity. He said, "All the maniacs in the world write to me," she wrote.

    Lighter moments recounted The diary also recounts how, on his 75th birthday, Einstein received a parrot as gift. After deciding the bird was depressed, Einstein tried alter its mood by telling bad jokes. At times, Einstein would pretend to be sick in bed so he would not have to pose with visitors who wanted photographs. Einstein still enjoyed himself even when real illness did take hold. Einstein¹s health began to fail, but he continued to indulge in what remained his favorite of all pastimes, sailing. Seldom did I see him so gay and in so light a mood as in this strangely primitive little boat, Fantova wrote. Einstein also wrote Fantova poems, some of which are in the diary.

    Einstein, with his second wife Elsa, had arrived in Princeton in 1933 at the newly formed Institute for Advanced Study. Elsa died three years later. Fantova first met Einstein in 1929 in Berlin. She arrived in the United States alone in 1939 and, at Einstein¹s urging, attended library school at the University of North Carolina.

Einstein the Greatest

November 29, 1999 - BBC

Albert Einstein has been voted the greatest physicist of all time in an end of the millennium poll, pushing Sir Isaac Newton into second place.

The survey was conducted among 100 of today's leading physicists.

All-time top ten:

1. Albert Einstein
2. Isaac Newton
3. James Clerk Maxwell
4. Niels Bohr
5. Werner Heisenberg
6. Galileo Galilei
7. Richard Feynman
8. Paul Dirac
9. Erwin Schrödinger
10. Ernest Rutherford

"Einstein's special and general theories of relativity completely overturned previous conceptions of a universal, immutable space and time, and replaced them with a startling new framework in which space and time are fluid and malleable," said physicist Brian Greene from Columbia University, US, who participated in the poll for Physics World magazine.

Peter Rodgers, Editor of Physics World, said: "Einstein and Newton were always going to be one and two but what was surprising about the top 10 was that there were seven out and out theorists."

The top 10 includes three British scientists: Newton, James Clerk Maxwell and Paul Dirac. New Zealander Ernest Rutherford, who did much of his work in the UK, also makes the list, at 10.

Hawking and Archimedes

A parallel survey of rank-and-file physicists by the site PhysicsWeb gave the top spot to Newton and also included Michael Faraday.

Neither list included any living scientist, but Stephen Hawking was rated at 16 by PhysicsWeb users, just behind Archimedes.

Paul Guinnessy, editor of PhysicsWeb, said: "My two biggest surprises were the inclusion of Stephen Hawking, as I think more time is needed to see whether his scientific contributions will last, and the low number of votes for Marie Curie and Ernest Rutherford.

"Both these physicists had a dramatic impact not only on scientific achievements but in the students they taught and drew into physics. Rutherford's lab in particular had a number of students who were awarded Nobel prizes at a later date."

Big science

The three most important discoveries in physics are quantum mechanics, Einstein's theory of general relativity and Newton's mechanics and gravitation.

Quantum computation pioneer David Deutsch of Oxford University said: "In each of these three cases, the discovery in question not only revolutionised the branch of physics that it nominally addressed, but also provided a framework so deep and universal that all subsequent theories in physics have been formulated within it."

Asked about their careers, the physicists said they were mostly happy. Over 70% of respondents said they would study physics if they were starting university this year. But 17% said they would not, with one Japanese researcher commenting: "I worked too hard. I want to enjoy life next time."

However, asked for the biggest problem in physics, one respondent joked "getting tenure or quantum gravity".

As is traditional, the physicists had a high opinion of their subject, calling it "the most grandiose science", "the most fascinating activity for our brain" and "still the most fundamental of all sciences".

But the biological sciences did appeal to some. Michael Green, a particle theorist at Cambridge University, said: "There is something attractive about a subject that is still in a relatively primitive state."




Einstein's brain found to be anatomically distinct

Einstein allowed his brain to be studied after his death

AP - June 17, 1999

We always thought something must have made Albert Einstein smarter than the rest of us. Now, scientists have found that one part of his brain was indeed physically extraordinary.

In the only study ever conducted of the overall anatomy of Einstein's brain, scientists at McMaster University in Ontario, Canada, discovered that the part of the brain thought to be related to mathematical reasoning - the inferior parietal region - was 15 percent wider on both sides than normal.

Furthermore, they found that the groove that normally runs from the front of the brain to the back did not extend all the way in Einstein's case. That finding could have applications even to those with more pedestrian levels of intelligence.

Einstein thought in images

"That kind of shape was not observed in any one of our brains and is not depicted in any atlas of the human brain," said Sandra Witelson, a neuroscientist who led the study, published in this week's issue of The Lancet, a British medical journal.

"But it shouldn't be seen as anatomy is destiny," she added. "We also know that environment has a very important role to play in learning and brain development. But what this is telling us is that environment isn't the only factor."

The findings may point to the importance of the inferior parietal region, Witelson said.

While the differences may be extraordinary between Einstein and everyone else, there may be more subtle, even microscopic, differences when the anatomies of the brains of people who don't fall into the genius category are compared with each other, she said.

The researchers compared the founder of the theory of relativity's brain with the preserved brains of 35 men and 56 women known to have normal intelligence when they died.

With the men's brains, they conducted two separate comparisons - first between Einstein's brain and all the men, and next between his brain and those of the eight men who were similar in age to Einstein when they died.

They found that, overall, Einstein's brain was the same weight and had the same measurements from front to back as all the other men, which Witelson said confirms the belief of many scientists that focusing on overall brain size as an indicator of intelligence is not the way to go.

Witelson theorized that the partial absence of the groove in Einstein's brain may be the key, because it might have allowed more neurons in this area to establish connections between each other and work together more easily.

She said it is likely that the groove, known as the sulcus, was always absent in that part of Einstein's brain, rather than shrinking away as a result of his intelligence, because, as one of the two or three landmarks in the human brain, it appears very early in life.

"We don't know if every brilliant physicist and mathematician will have this same anatomy," Witelson said. "It fits and it makes a compelling story, but it requires further proof."

John Gabrieli, an associate professor of psychology at Stanford University who was not connected with the study, said the finding relating to the groove and connections between the neurons in the brain may be the key.

"We don't have a clue, so anything that is suggested is interesting," he said. "There must have been something about his brain that made him so brilliant."

Brilliance of the kind Einstein possessed is so extreme, however, that although the findings may give a clue to the neurology of genius, whether they could apply to normal differences in intelligence is more doubtful, Gabrieli said.

Witelson said the next stage is to scan the brains of living mathematicians and look for minute differences.

Witelson and her team acquired Einstein's brain after they were contacted by its keeper, scientist John Harvey, who had read about the university's brain research.

Harvey was a pathologist working at a small hospital in Princeton, N.J., when Einstein died in 1955 at the age of 76. Harvey performed the autopsy, determined Einstein died of natural causes and took the brain home with him.

Some parts of the brain were given to scientists, but no major study was ever conducted, until now.

Thomas Alva Edison

Thomas Alva Edison


Thomas Alva Edison (February 11, 1847 - Oct. 18, 1931) was an American inventor who, singly or jointly, held a world record 1,093 patents. In addition, he created the world's first industrial research laboratory.

Edison was the quintessential American inventor in the era of Yankee ingenuity.

He began his career in 1863, in the adolescence of the telegraph industry, when virtually the only source of electricity was primitive batteries putting out a low-voltage current.

Before he died, in 1931, he had played a critical role in introducing the modern age of electricity. From his laboratories and workshops emanated the phonograph, the carbon-button transmitter for the telephone speaker and microphone, the incandescent lamp, a revolutionary generator of unprecedented efficiency, the first commercial electric light and power system, an experimental electric railroad, and key elements of motion-picture apparatus, as well as a host of other inventions.

Edison was the seventh and last child--the fourth surviving--of Samuel Edison, Jr., and Nancy Elliot Edison. At an early age he developed hearing problems, which have been variously attributed but were most likely due to a familial tendency to mastoiditis. Whatever the cause, Edison's deafness strongly influenced his behaviour and career, providing the motivation for many of his inventions.

Early years

In 1854 Samuel Edison became the lighthouse keeper and carpenter on the Fort Gratiot military post near Port Huron, Mich., where the family lived in a substantial home. Alva, as the inventor was known until his second marriage, entered school there and attended sporadically for five years. He was imaginative and inquisitive, but because much instruction was by rote and he had difficulty hearing, he was bored and was labeled a misfit.

To compensate, he became an avid and omnivorous reader. Edison's lack of formal schooling was not unusual. At the time of the Civil War the average American had attended school a total of 434 days--little more than two years' schooling by today's standards.

In 1859 Edison quit school and began working as a trainboy on the railroad between Detroit and Port Huron. Four years earlier, the Michigan Central had initiated the commercial application of the telegraph by using it to control the movement of its trains, and the Civil War brought a vast expansion of transportation and communication. Edison took advantage of the opportunity to learn telegraphy and in 1863 became an apprentice telegrapher.

Messages received on the initial Morse telegraph were inscribed as a series of dots and dashes on a strip of paper that was decoded and read, so Edison's partial deafness was no handicap. Receivers were increasingly being equipped with a sounding key, however, enabling telegraphers to "read" messages by the clicks.

The transformation of telegraphy to an auditory art left Edison more and more disadvantaged during his six-year career as an itinerant telegrapher in the Midwest, the South, Canada, and New England. Amply supplied with ingenuity and insight, he devoted much of his energy toward improving the inchoate equipment and inventing devices to facilitate some of the tasks that his physical limitations made difficult.

By January 1869 he had made enough progress with a duplex telegraph (a device capable of transmitting two messages simultaneously on one wire) and a printer, which converted electrical signals to letters, that he abandoned telegraphy for full-time invention and entrepreneurship.

Edison moved to New York City, where he initially went into partnership with Frank L. Pope, a noted electrical expert, to produce the Edison Universal Stock Printer and other printing telegraphs. Between 1870 and 1875 he worked out of Newark, N.J., and was involved in a variety of partnerships and complex transactions in the fiercely competitive and convoluted telegraph industry, which was dominated by the Western Union Telegraph Company. As an independent entrepreneur he was available to the highest bidder and played both sides against the middle. During this period he worked on improving an automatic telegraph system for Western Union's rivals.

The automatic telegraph, which recorded messages by means of a chemical reaction engendered by the electrical transmissions, proved of limited commercial success, but the work advanced Edison's knowledge of chemistry and laid the basis for his development of the electric pen and mimeograph, both important devices in the early office machine industry, and indirectly led to the discovery of the phonograph.

Under the aegis of Western Union he devised the quadruplex, capable of transmitting four messages simultaneously over one wire, but railroad baron and Wall Street financier Jay Gould, Western Union's bitter rival, snatched the quadruplex from the telegraph company's grasp in December 1874 by paying Edison more than $100,000 in cash, bonds, and stock, one of the larger payments for any invention up to that time. Years of litigation followed.

Menlo Park

Although Edison was a sharp bargainer, he was a poor financial manager, often spending and giving away money more rapidly than he earned it.

In 1871 he married 16-year-old Mary Stilwell, who was as improvident in household matters as he was in business, and before the end of 1875 they were in financial difficulties.

To reduce his costs and the temptation to spend money, Edison brought his now-widowed father from Port Huron to build a 2 1/2-story laboratory and machine shop in the rural environs of Menlo Park, N.J.--12 miles south of Newark--where he moved in March 1876.

Accompanying him were two key associates, Charles Batchelor and John Kruesi.

Batchelor, born in Manchester in 1845, was a master mechanic and draftsman who complemented Edison perfectly and served as his "ears" on such projects as the phonograph and telephone. He was also responsible for fashioning the drawings that Kruesi, a Swiss-born machinist, translated into models.

Edison experienced his finest hours at Menlo Park. While experimenting on an underwater cable for the automatic telegraph, he found that the electrical resistance and conductivity of carbon (then called plumbago) varied according to the pressure it was under.

This was a major theoretical discovery, which enabled Edison to devise a "pressure relay" using carbon rather than the usual magnets to vary and balance electric currents.

In February 1877 Edison began experiments designed to produce a pressure relay that would amplify and improve the audibility of the telephone, a device that Edison and others had studied but which Alexander Graham Bell was the first to patent, in 1876.

By the end of 1877 Edison had developed the carbon-button transmitter that is still used in telephone speakers and microphones.

The phonograph

Edison invented many items, including the carbon transmitter, in response to specific demands for new products or improvements. But he also had the gift of serendipity: when some unexpected phenomenon was observed, he did not hesitate to halt work in progress and turn off course in a new direction.

This was how, in 1877, he achieved his most original discovery, the phonograph.

Because the telephone was considered a variation of acoustic telegraphy, Edison during the summer of 1877 was attempting to devise for it, as he had for the automatic telegraph, a machine that would transcribe signals as they were received, in this instance in the form of the human voice, so that they could then be delivered as telegraph messages. (The telephone was not yet conceived as a general, person-to-person means of communication.)

Some earlier researchers, notably the French inventor Léon Scott, had theorized that each sound, if it could be graphically recorded, would produce a distinct shape resembling shorthand, or phonography ("sound writing"), as it was then known. Edison hoped to reify this concept by employing a stylus-tipped carbon transmitter to make impressions on a strip of paraffined paper.

To his astonishment, the scarcely visible indentations generated a vague reproduction of sound when the paper was pulled back beneath the stylus.

Edison unveiled the tinfoil phonograph, which replaced the strip of paper with a cylinder wrapped in tinfoil, in December 1877. It was greeted with incredulity. Indeed, a leading French scientist declared it to be the trick device of a clever ventriloquist.

The public's amazement was quickly followed by universal acclaim. Edison was projected into worldwide prominence and was dubbed the Wizard of Menlo Park, although a decade passed before the phonograph was transformed from a laboratory curiosity into a commercial product.

The electric light

Another offshoot of the carbon experiments reached fruition sooner. Samuel Langley, Henry Draper, and other American scientists needed a highly sensitive instrument that could be used to measure minute temperature changes in heat emitted from the Sun's corona during a solar eclipse along the Rocky Mountains on July 29, 1878. To satisfy those needs Edison devised a "microtasimeter" employing a carbon button.

This was a time when great advances were being made in electric arc lighting, and during the expedition, which Edison accompanied, the men discussed the practicality of "subdividing" the intense arc lights so that electricity could be used for lighting in the same fashion as with small, individual gas "burners."

The basic problem seemed to be to keep the burner, or bulb, from being consumed by preventing it from overheating. Edison thought he would be able to solve this by fashioning a microtasimeter-like device to control the current.

He boldly announced that he would invent a safe, mild, and inexpensive electric light that would replace the gaslight.

The incandescent electric light had been the despair of inventors for 50 years, but Edison's past achievements commanded respect for his boastful prophecy. Thus, a syndicate of leading financiers, including J.P. Morgan and the Vanderbilts, established the Edison Electric Light Company and advanced him $30,000 for research and development.

Edison proposed to connect his lights in a parallel circuit by subdividing the current, so that, unlike arc lights, which were connected in a series circuit, the failure of one light bulb would not cause a whole circuit to fail. Some eminent scientists predicted that such a circuit could never be feasible, but their findings were based on systems of lamps with low resistance - the only successful type of electric light at the time.

Edison, however, determined that a bulb with high resistance would serve his purpose, and he began searching for a suitable one.

He had the assistance of 26-year-old Francis Upton, a graduate of Princeton University with an M.A. in science. Upton, who joined the laboratory force in December 1878, provided the mathematical and theoretical expertise that Edison himself lacked. (Edison later revealed, "At the time I experimented on the incandescent lamp I did not understand Ohm's law."

On another occasion he said, "I do not depend on figures at all. I try an experiment and reason out the result, somehow, by methods which I could not explain.")

By the summer of 1879 Edison and Upton had made enough progress on a generator--which, by reverse action, could be employed as a motor--that Edison, beset by failed incandescent lamp experiments, considered offering a system of electric distribution for power, not light.

By October Edison and his staff had achieved encouraging results with a complex, regulator-controlled vacuum bulb with a platinum filament, but the cost of the platinum would have made the incandescent light impractical.

While experimenting with an insulator for the platinum wire, they discovered that, in the greatly improved vacuum they were now obtaining through advances made in the vacuum pump, carbon could be maintained for some time without elaborate regulatory apparatus.

Advancing on the work of Joseph Wilson Swan, an English physicist, Edison found that a carbon filament provided a good light with the concomitant high resistance required for subdivision. Steady progress ensued from the first breakthrough in mid-October until the initial demonstration for the backers of the Edison Electric Light Company on December 3.

It was, nevertheless, not until the summer of 1880 that Edison determined that carbonized bamboo fibre made a satisfactory material for the filament, although the world's first operative lighting system had been installed on the steamship Columbia in April.

The first commercial land-based "isolated" (single-building) incandescent system was placed in the New York printing firm of Hinds and Ketcham in January 1881.

In the fall a temporary, demonstration central power system was installed at the Holborn Viaduct in London, in conjunction with an exhibition at the Crystal Palace. Edison himself supervised the laying of the mains and installation of the world's first permanent, commercial central power system in lower Manhattan, which became operative in September 1882.

Although the early systems were plagued by problems and many years passed before incandescent lighting powered by electricity from central stations made significant inroads into gas lighting, isolated lighting plants for such enterprises as hotels, theatres, and stores flourished--as did Edison's reputation as the world's greatest inventor.

One of the accidental discoveries made in the Menlo Park laboratory during the development of the incandescent light anticipated the British physicist J.J. Thomson's discovery of the electron 15 years later.

In 1881-82 William J. Hammer, a young engineer in charge of testing the light globes, noted a blue glow around the positive pole in a vacuum bulb and a blackening of the wire and the bulb at the negative pole. This phenomenon was first called "Hammer's phantom shadow," but when Edison patented the bulb in 1883 it became known as the "Edison effect."

Scientists later determined that this effect was explained by the thermionic emission of electrons from the hot to the cold electrode, and it became the basis of the electron tube and laid the foundation for the electronics industry.

Edison had moved his operations from Menlo Park to New York City when work commenced on the Manhattan power system. Increasingly, the Menlo Park property was used only as a summer home.

In August 1884 Edison's wife, Mary, suffering from deteriorating health and subject to periods of mental derangement, died there of "congestion of the brain," apparently a tumour or hemorrhage. Her death and the move from Menlo Park roughly mark the halfway point of Edison's life.

The Edison laboratory

A widower with three young children, Edison, on Feb. 24, 1886, married 20-year-old Mina Miller, the daughter of a prosperous Ohio manufacturer. He purchased a hilltop estate in West Orange, N.J., for his new bride and constructed nearby a grand, new laboratory, which he intended to be the world's first true research facility.

There, he produced the commercial phonograph, founded the motion-picture industry, and developed the alkaline storage battery. Nevertheless, Edison was past the peak of his productive period.

A poor manager and organizer, he worked best in intimate, relatively unstructured surroundings with a handful of close associates and assistants; the West Orange laboratory was too sprawling and diversified for his talents. Furthermore, as a significant portion of the inventor's time was taken up by his new role of industrialist, which came with the commercialization of incandescent lighting and the phonograph, electrical developments were passing into the domain of university-trained mathematicians and scientists.

Above all, for more than a decade Edison's energy was focused on a magnetic ore-mining venture that proved the unquestioned disaster of his career.

The first major endeavor at the new laboratory was the commercialization of the phonograph, a venture launched in 1887 after Alexander Graham Bell, his cousin Chichester, and Charles Tainter had developed the graphophone--an improved version of Edison's original device--which used waxed cardboard instead of tinfoil.

Two years later, Edison announced that he had "perfected" the phonograph, although this was far from true. In fact, it was not until the late 1890s, after Edison had established production and recording facilities adjacent to the laboratory, that all the mechanical problems were overcome and the phonograph became a profitable proposition.

In the meantime, Edison conceived the idea of popularizing the phonograph by linking to it in synchronization a zoetrope, a device that gave the illusion of motion to photographs shot in sequence. He assigned the project to William K.L. Dickson, an employee interested in photography, in 1888.

After studying the work of various European photographers who also were trying to record motion, Edison and Dickson succeeded in constructing a working camera and a viewing instrument, which were called, respectively, the Kinetograph and the Kinetoscope.

Synchronizing sound and motion proved of such insuperable difficulty, however, that the concept of linking the two was abandoned, and the silent movie was born. Edison constructed at the laboratory the world's first motion-picture stage, nicknamed the "Black Maria," in 1893, and the following year Kinetoscopes, which had peepholes that allowed one person at a time to view the moving pictures, were introduced with great success.

Rival inventors soon developed screen-projection systems that hurt the Kinetoscope's business, however, so Edison acquired a projector developed by Thomas Armat and introduced it as "Edison's latest marvel, the Vitascope."

Another derivative of the phonograph was the alkaline storage battery, which Edison began developing as a power source for the phonograph at a time when most homes still lacked electricity.

Although it was 20 years before all the difficulties with the battery were solved, by 1909 Edison was a principal supplier of batteries for submarines and electric vehicles and had even formed a company for the manufacture of electric automobiles.

In 1912 Henry Ford, one of Edison's greatest admirers, asked him to design a battery for the self-starter, to be introduced on the Model T. Ford's request led to a continuing relationship between these two Americans, and in October 1929 he staged a 50th-anniversary celebration of the incandescent light that turned into a universal apotheosis for Edison.

Most of Edison's successes involved electricity or communication, but throughout the late 1880s and early 1890s the Edison Laboratory's top priority was the magnetic ore-separator. Edison had first worked on the separator when he was searching for platinum for use in the experimental incandescent lamp.

The device was supposed to cull platinum from iron-bearing sand. During the 1880s iron ore prices rose to unprecedented heights, so that it appeared that, if the separator could extract the iron from unusable low-grade ores, then abandoned mines might profitably be placed back in production.

Edison purchased or acquired rights to 145 old mines in the east and established a large pilot plant at the Ogden mine, near Ogdensburg, N.J.

He was never able to surmount the engineering problems or work the bugs out of the system, however, and when ore prices plummeted in the mid-1890s he gave up on the idea. By then he had liquidated all but a small part of his holdings in the General Electric Company, sometimes at very low prices, and had become more and more separated from the electric lighting field.

Failure could not discourage Edison's passion for invention, however. Although none of his later projects were as successful as his earlier ones, he continued to work even in his 80s.

Assessment

The thrust of Edison's work may be seen in the clustering of his patents: 389 for electric light and power, 195 for the phonograph, 150 for the telegraph, 141 for storage batteries, and 34 for the telephone. His life and achievements epitomize the ideal of applied research.

He always invented for necessity, with the object of devising something new that he could manufacture. The basic principles he discovered were derived from practical experiments, invariably by chance, thus reversing the orthodox concept of pure research leading to applied research.

Edison's role as a machine shop operator and small manufacturer was crucial to his success as an inventor.

Unlike other scientists and inventors of the time, who had limited means and lacked a support organization, Edison ran an inventive establishment.

He was the antithesis of the lone inventive genius, although his deafness enforced on him an isolation conducive to conception. His lack of managerial ability was, in an odd way, also a stimulant.

As his own boss, he plunged ahead on projects more prudent men would have shunned, then tended to dissipate the fruits of his inventiveness, so that he was both free and forced to develop new ideas. Few men have matched him in the positiveness of his thinking.

Edison never questioned whether something might be done, only how.

Edison's career, the fulfillment of the American dream of rags-to-riches through hard work and intelligence, made him a folk hero to his countrymen.

In temperament he was an uninhibited egotist, at once a tyrant to his employees and their most entertaining companion, so that there was never a dull moment with him.

He was charismatic and courted publicity, but he had difficulty socializing and neglected his family. His shafts at the expense of the "long-haired" fraternity of theorists sometimes led formally trained scientists to deprecate him as anti-intellectual; yet he employed as his aides, at various times, a number of eminent mathematical physicists, such as Nikola Tesla and A.E. Kennelly.

The contradictory nature of his forceful personality, as well as such eccentricities as his ability to catnap anywhere, contributed to his legendary status.

By the time he was in his middle 30s Edison was said to be the best-known American in the world.

When he died he was venerated and mourned as the man who, more than any other, had laid the basis for the technological and social revolution of the modern electric world.

Patents

Edison executed the first of his 1,093 successful U.S. patent applications on 13 October 1868, at the age of 21. (For a graphic representation of his annual output.

He filed an estimated 500–600 unsuccessful or abandoned applications as well. Unfortunately, the names given Edison's patents are too irregular to make simple word searches an accurate means of finding patents for particular technologies. His issued patents are presented here in three listsóby execution date, patent date, and subject. The execution and patent date lists are each presented in six parts to make the files less cumbersome.

He execution date of a patent application is the date on which the inventor signs the application, and hence is the date closest to the actual inventive activity. However, in his early years Edison did not always rush to his patent lawyer with an invention, especially if there was little competition for the invention or he was feeling broke and unable to pay the various fees involved in an application. In a few cases Edison removed some of the claims from an original application and filed a new application to cover those claims. The execution date of such a patent can be considerably later than that of the original application even though the patent covers designs from the earlier date.

The subject lists are necessarily somewhat arbitrary. They are arranged by execution date. A few patents appear in two listsófor example, Patent 142,999 is for a battery Edison developed for telegraphy, and it is under "Batteries" and "Telegraphy and Telephony."
