Benjamin Franklin's celebratedAutobiography, published after his death, is one of the greatest autobiographies of all time...but it was incomplete. Franklin ended his life's story in 1757, when he was only fifty-one. He planned to write more--a lot more, but never did. He lived another thirty-three full, eventful, and dramatic years, some of the most dramatic years in American history, years in which Franklin was America's advocate in London, represented Pennsylvania in the Continental Congress, and was America'swartime ambassador to France. During these years Franklin also helped write our nation's Constitution and planned an American Empire that would displace the British.
