Benjamin Franklin. Started with nothing and build a fortune as an entrepreneur and author. Then became a philanthropist and created the first public library un the USA, the University or Pennsylvania, and a dozen other institutions that still exists today. Then he invented a number of important things, probably chief among them the lightning rod without which there would be no skyscrapers today. The he charmed the French into joining the revolution with us and toppling the British. Absolute genius and legend.
For those who mentioned Franklin, his autobiography is out there as audio.

It’s a really good recording too. I think Franklin deserves another as there are plenty of pre-1923 biogs of Franklin, but I will be going another direction.
