Franklin's first trade was printing; he published the Pennsylvania Gazette from 1729 and in 1733 started the immensely popular Poor Richard's Almanac. He represented the American colonists in London (1757-62, 1764-75) and on his return home actively promoted the revolutionary cause, being one of the five who drafted the Declaration of Independence (1776). Sent to win France's support for the Revolution, he brought about the vital alliance in 1778. He returned to take part in the Constitutional Convention (1787) and retired from public life the following year. Franklin found time to make important contributions to physical theory, identified lightning as an electrical charge, drew the first printed chart of the Gulf Stream, and invented bifocal spectacles and the lightning rod, among many other things.
