Mark Zuckerberg

Born on May 14, 1984, in White Plains, New York, Mark Zuckerberg co-founded the social-networking website Facebook out of his college dorm room. He left Harvard after his sophomore year to concentrate on the site, the user base of which has grown to more than 250 million people, making Zuckerberg a billionaire. The birth of Facebook was recently portrayed in the film The Social Network.

## Early life

Mark Elliot Zuckerberg was born on May 14, 1984, in White Plains, New York, into a comfortable, well-educated family, and raised in the nearby village of Dobbs Ferry. His father, Edward Zuckerberg, ran a dental practice attached to the family's home. His mother, Karen, worked as a psychiatrist before the birth of the couple's four children—Mark, Randi, Donna and Arielle.

Zuckerberg developed an interest in computers at an early age; when he was about 12, he used Atari BASIC to create a messaging program he named "Zucknet." His father used the program in his dental office, so that the receptionist could inform him of a new patient without yelling across the room. The family also used Zucknet to communicate within the house. Together with his friends, he also created computer games just for fun. "I had a bunch of friends who were artists," he said. "They'd come over, draw stuff, and I'd build a game out of it."

To keep up with Mark's burgeoning interest in computers, his parents hired private computer tutor David Newman to come to the house once a week and work with Mark. Newman later told reporters that it was hard to stay ahead of the prodigy, who began taking graduate courses at nearby Mercy College around this same time.

Zuckerberg later studied at Phillips Exeter Academy, an exclusive preparatory school in New Hampshire. There he showed talent in fencing, becoming the captain of the school's team. He also excelled in literature, earning a diploma in classics. Yet Zuckerberg remained fascinated by computers, and continued to work on developing new programs. While still in high school, he created an early version of the music software Pandora, which he called Synapse. Several companies—including AOL and Microsoft—expressed an interest in buying the software, and hiring the teenager before graduation. He declined the offers.

After graduating from Exeter in 2002, Zuckerberg enrolled at Harvard University. By his sophomore year at the ivy league institution, he had developed a reputation as the go-to software developer on campus. It was at that time that he built a program called CourseMatch, which helped students choose their classes based on the course selections of other users. He also invented Facemash, which compared the pictures of two students on campus and allowed users to vote on which one was more attractive. The program became wildly popular, but was later shut down by the school administration after it was deemed inappropriate.

Based on the buzz of his previous projects, three of his fellow students—Divya Narendra, and twins Cameron and Tyler Winklevoss—sought him out to work on an idea for a social networking site they called Harvard Connection. This site was designed to use information from Harvard's student networks in order to create a dating site for the Harvard elite. Zuckerberg agreed to help with the project, but soon dropped out to work on his own social networking site with friends Dustin Moskovitz, Chris Hughes and Eduardo Saverin.
