I'd argue that long after his business acumen is just a footnote, Bill Gates' charity work will stand him head and shoulders into the top people who've ever lived. He'll be remembered as a business tycoon probably among the likes of JP Morgan or Carnegie, but that will fade with time. His charity work, on the other hand, might eventually work out to save _tens of millions_ of lives. If the foundation prospers long enough to beat malaria and waterborne disease in the developing world, they'll re-shape the population of a continent. They may not only save more lives than anyone in history, but manage to save more lives than any dictator was able to end, which is a sadly astonishing achievement.
