Bill Gates
In 2006, Gates announced he was going to quit his job at Microsoft. This was so he could do more charity work with his wife, Melinda. Their charity is called the Bill and Melinda Gates Foundation. Gates' philanthropy projects have included vaccination of children in sub-Saharan Africa, scholarship programs in the United States, and a mission to help organize other billionaires to redistribute their wealth. He likes to give money and support to human rights, education, and technological innovation.
