Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is best known as one of four co-founders of the social networking site Facebook, of which he is chairman and chief executive.

Zuckerberg was born and raised in a Jewish household in New York state. While still in middle school in his early teens, he took up writing software programs as a hobby, beginning with BASIC, with help from his father. His father then hired a tutor to help his son develop his programming skills further. Zuckerberg's enjoyment in writing programs led him to developing computer games, writing a music player, and setting up a primitive home network he called "ZuckNet." His private tutor calls him a "prodigy." In high school he excelled in classic literature and science, while becoming proficient in four other languages. He was also captain of the school's fencing team.

He later enrolled in Harvard, majoring in computer science and sociology. In his sophomore year he wrote a program called Facemash as a "fun" project, letting students on the college's network vote on other students' photo attractiveness. It was shut down within days, but would become a template for his writing Facebook, a program he launched from his dormitory room. With the help of friends, including roommate Dustin Moskovitz, Facebook went national on other campuses, and they moved to Palo Alto, California. By 2010, the site had an estimated 500 million users worldwide. Zuckerberg and Facebook have since been involved in various legal disputes initiated by others who have claimed a share of the company's profits due to their help in setting it up. Zuckerberg is the largest individual shareholder with 28.4 percent of the common stock and controls 56.9 percent of the voting power. As of 2012^[update], his personal wealth was estimated at more than $19.1 billion, making him one of the world's youngest billionaires. Zuckerberg is one of the 30 richest people on Earth.
