Meet the famous diplomat who proved that lightning is form of electricity?

One of the leading figures of early American history, Benjamin Franklin (1706-90) was a statesman, author, publisher, scientist, inventor and diplomat. Born into a Boston family of modest means, Franklin had little formal education. He went on to start a successful printing business in Philadelphia and grew wealthy. Franklin was deeply active in public affairs in his adopted city, where he helped launch a lending library, hospital and college, and garnered acclaim for his experiments with electricity, among other projects. During the American Revolution, he served in the Second Continental Congress and helped draft the Declaration of Independence in 1776. He also negotiated the 1783 Treaty of Paris that ended the Revolutionary War (1775-83).
In 1787, in his final significant act of public service, he was a delegate to the convention that produced the U.S. Constitution.
In 1748, Franklin, then 42 years old, had expanded his printing business throughout the colonies and become successful enough to stop working. Retirement allowed him to concentrate on public service and also pursue more fully his longtime interest in science. In the 1740s, he conducted experiments that contributed to the understanding of electricity, and invented the lightning rod, which protected buildings from fires caused by lightning. In 1752, he conducted his famous kite experiment and demonstrated that lightning is electricity. Franklin also coined a number of electricity-related terms, including battery, charge and conductor.
In addition to electricity, Franklin studied a number of other topics, including ocean currents, meteorology, causes of the common cold and refrigeration. He developed the Franklin stove, which provided more heat while using less fuel than other stoves, and bifocal eyeglasses, which allow for distance and reading use. In the early 1760s, Franklin invented a musical instrument called the glass armonica. Composers such as Ludwig Beethoven (1770-1827) and Wolfgang Mozart (1756-91) wrote music for Franklin’s armonica; however, by the early part of the 19th century, the once-popular instrument had largely fallen out of use.
