Facebook’s founder Mark Zuckerberg might have been portrayed as a selfish snob in the movie The Social Network, but he and his wife were recently named the most generous Americans of 2013. They gave away about 18 million Facebook shares (pieces of the company), which are worth over $990 million, to a nonprofit organization in California.
According to The Chronicle of Philanthropy, that was the single largest donation on public record made in the year 2013. They’re also the youngest ever to be number one on Philanthropy’s top 50 list. Some other big givers of the year didn’t make the year’s top 50 list because their donations were counted as part of pledges from previous years. For example, Microsoft CEO Bill Gates gave almost $200 million last year, but that’s part of a $3 billion donation he and his wife made back in 2004.
Other names on the list include Nike chairman Philip Knight, New York’s former Mayor Michael Bloomberg, and a man named George Mitchell, who made his fortune in energy and real estate.
About 60% of the donations were for colleges and research projects. Another 38% of people on the list donated to Giving Pledge, a charity started by Bill Gates and investor Warren Buffett in 2010.
