Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is best known for co-creating the social networking site Facebook, of which he is chief executive and president. It was co-founded as a private company in 2004 by Zuckerberg and classmates Dustin Moskovitz, Eduardo Saverin, and Chris Hughes while they were students at Harvard University. In 2010, Zuckerberg was named Time magazine's Person of the Year. As of 2011, his personal wealth was estimated to be $13.5 billion.
Zuckerberg was born in 1984 in White Plains, New York to Karen, a psychiatrist, and Edward Zuckerberg, a dentist. He and his three sisters, Randi, Donna, and Arielle, were brought up in Dobbs Ferry, New York. Zuckerberg was raised Jewish and had his bar mitzvah when he turned 13, although he has since described himself as an atheist.
At Ardsley High School, Zuckerberg had excelled in the classics before transferring to Phillips Exeter Academy in his junior year, where he won prizes in science (math, astronomy and physics) and Classical studies (on his college application, Zuckerberg listed as non-English languages he could read and write: French, Hebrew, Latin, and ancient Greek) and was a fencing star and captain of the fencing team. In college, he was known for reciting lines from epic poems such as The Iliad.
