In no particular order: Richard Feynman - For his integrity and for insisting on skepticism and rigor in everything. Robert Heinlein - Along with John W. Campbell, he brought science fiction away from ray-guns and bug-eyed monsters and made it interesting and thought-provoking. A lot of people went into science and engineering because of his influence. Raoul Wallenberg - He stood up to the Nazis and Hungarian fascists to prevent thousands of people from being sent to the death camps. Douglas Bader - PG mentioned him in his essay; this is a man who lost his legs in a flying accident. His disability didn't stop him from joining the Royal Air Force and piloting a fighter plane during the War. Not once did he feel sorry for himself; instead he was flying over Europe killing Nazis. Norm Zadah - He went from being a professor of CS at Stanford to running a hedge fund and being a championship poker player. When a female friend of his was rejected from Playboy, he went ahead and started his own magazine, Perfect 10. So far, he's lost nearly $46 million on Perfect 10, and he's switched to web distribution, but he doesn't care, he likes his work. Truly a renaissance man.
