Bill Gates.
Not only a brilliant businessman, but also a great philanthropist:
"Through the BMGF – as well as on a personal basis – Gates has given away $41bn, representing 46 percent of his total wealth. This figure is set to almost double if Gates fulfils his 2010 pledge to donate 95 percent of his wealth before he dies."
