Who was Benjamin Franklin?
January 6, 1706] – April 17, 1790) was an American polymath who was active as a writer, scientist, inventor, statesman, diplomat, printer, publisher and political philosopher. Among the leading intellectuals of his time, Franklin was one of the Founding Fathers of the United States and the first United States Postmaster General. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia 's first fire department, and the University of Pennsylvania. Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States Ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical 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 historian 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."
When did Benjamin Franklin discover electricity?
Franklin started exploring the phenomenon of electricity in 1746 when he saw some of Archibald Spencer 's lectures using static electricity for illustrations. Franklin proposed that "vitreous" and "resinous" electricity were not different types of " electrical fluid " (as electricity was called then), but the same "fluid" under different pressures. (The same proposal was made independently that same year by William Watson .) Franklin 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 1748, he constructed a multiple plate capacitor, that he called an "electrical battery" (not to be confused with Volta's pile) by placing eleven panes of glass sandwiched between lead plates, suspended with silk cords and connected by wires.
What did Benjamin Franklin do after Denham died?
Upon Denham's death, Franklin returned to his former trade. In 1728, Franklin had set up a printing house in partnership with Hugh Meredith; the following year he became 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, and his adroit cultivation of a positive image as an industrious and intellectual young man, earned him a great deal of social respect. But even after Franklin had achieved fame as a scientist and statesman, he habitually signed his letters with the unpretentious 'B. Franklin, Printer.'
How did Benjamin Franklin prove lightning is electricity?
Franklin 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-tall (12 m) iron rod instead of a kite, and he extracted electrical sparks from a cloud. On June 15, 1752, Franklin may possibly have conducted his well-known kite experiment in Philadelphia, successfully extracting sparks from a cloud. Franklin described the experiment in the Pennsylvania Gazette on October 19, 1752, without mentioning that he himself had performed it. This account was read to the Royal Society on December 21 and printed as such in the Philosophical Transactions. Joseph Priestley published an account with additional details in his 1767 History and Present Status of Electricity. Franklin was careful to stand on an insulator, keeping dry under a roof to avoid the danger of electric shock. Others, such as Prof. Georg Wilhelm Richmann in Russia, were indeed electrocuted in performing lightning experiments during the months immediately following Franklin's experiment.
