Who is Mark Zuckerberg ?

Zuckerberg's marriage to longtime girlfriend Priscilla Chan was quite the surprise for friends and family--guests were told they were being invited over to celebrate Chan's medical school graduation, but in reality they ended up attending the pair's wedding.

Instead, he focused on expanding the site, opening up his project to outside developers and adding more features.

Zuckerberg later studied at Phillips Exeter Academy, an exclusive preparatory school in New Hampshire.

Similar to Steve Jobs, Mark Zuckerberg has a $1 annual salary as CEO of Facebook.

Zuckerberg seemed to be going nowhere but up, however in 2006, the business mogul faced his first big hurdle.

There he showed talent in fencing, becoming the captain of the school's team.

Zuckerberg was Time magazine's "Person of the Year" in 2010 and in 2013, Facebook made the Fortune 500 list for the first time--making Zuckerberg, at the age of 28, the youngest CEO on the list.

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.

Zuckerberg is currently 10 on Forbe's list of the 400 richest Americans.

The creators of Harvard Connection claimed that Zuckerberg stole their idea, and insisted the software developer needed to pay for their business losses.

Zuckerberg maintained that the ideas were based on two very different types of social networks but, after lawyers searched Zuckerberg's records, incriminating Instant Messages revealed that Zuckerberg may have intentionally stolen the intellectual property of Harvard Connection and offered Facebook users' private information to his friends.

Time at Harvard

Zuckerberg later apologized for the incriminating messages, saying he regretted them. "If you're going to go on to build a service that is influential and that a lot of people rely on, then you need to be mature, right?" he said in an interview with The New Yorker. "I think I've grown and learned a lot."

After graduating from Exeter in 2002, Zuckerberg enrolled at Harvard University.

Although an initial settlement of $65 million was reached between the two parties, the legal dispute over the matter continued well into 2011, after Narendra and the Winklevosses claimed they were misled in regards to the value of their stock.

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,

Zuckerberg faced yet another personal challenge when the 2009 book The Accidental Billionaires, by writer Ben Mezrich, hit stores.

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.

Mezrich was heavily criticized for his re-telling of Zuckerberg's story, which used invented scenes, re-imagined dialogue and fictional characters.

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.

Regardless of how true-to-life the story was, Mezrich managed to sell the rights of the tale to screenwriter Aaron Sorkin, and the critically acclaimed film The Social Network received eight Academy Award nominations.

Zuckerberg objected strongly to the film's narrative, and later told a reporter at The New Yorker that many of the details in the film were inaccurate.

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.

For example, Zuckerberg had been dating longtime girlfriend Priscilla Chan, a Chinese-American medical student he met at Harvard, since 2003.
