Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer, Internet entrepreneur, and philanthropist. He is the chairman, chief executive, and co-founder of the social networking website Facebook.^[4][5] His personal wealth, as of December 2015, is estimated to be $46 billion.^[3]

Together with his college roommates and fellow Harvard University students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, he launched Facebook from Harvard's dormitory rooms.^[6] The group then introduced Facebook to other campuses. Facebook expanded rapidly, with one billion users by 2012. Zuckerberg was involved in various legal disputes that were initiated by others in the group, who claimed a share of the company based upon their involvement during the development phase of Facebook.

In December 2012, Zuckerberg and his wife Priscilla Chan announced they would give the majority of their wealth over the course of their lives to "advancing human potential and promoting equality" in the spirit of The Giving Pledge.^[7] On December 1, 2015, they announced they would give 99% of their Facebook shares (worth about $45 billion at the time) to the Chan Zuckerberg Initiative.^[8][9]

Since 2010, Time magazine has named Zuckerberg among the 100 wealthiest and most influential people in the world as a part of its Person of the Year distinction.^[10][11][12]
