Harvard & Facemash

Two years, three programs, one disciplinary hearing — and the launch that changed the internet.

Arrival

Zuckerberg enrolled at Harvard in the fall of 2002, concentrating in psychology with heavy computer-science coursework, and moved into Kirkland House. He arrived already a serious programmer, and he programmed the way some students played pickup sports — constantly, socially, for the fun of it.

CourseMatch and the pattern

His first campus hit was CourseMatch, a site that let students see which courses their friends were taking and form study groups. It spread by word of mouth through the dorms. The pattern — build for one community, watch it spread through existing social ties — would become the Facebook growth playbook: Harvard first, then other Ivies, then all colleges, then high schools, then everyone.

Facemash

In October 2003, over a weekend, Zuckerberg built Facemash. The concept was crude: it scraped photos of students from the online “facebook” face books of Harvard’s houses and presented two at a time for visitors to vote on which was more attractive. Traffic overwhelmed parts of Harvard’s network; the site was shut down within days.

The fallout was serious. Harvard administrators charged him with breaching security, violating copyright, and violating individual privacy. He appeared before the Administrative Board — Harvard’s disciplinary body — facing possible expulsion. He was not expelled; he received a lesser sanction. In later interviews Zuckerberg has called Facemash a youthful mistake and expressed regret, while noting the episode taught him how quickly a product can outrun its creator’s intentions.

On the record vs. the film: The Social Network (2010) compresses the Facemash episode into a revenge-driven origin story. The documented record — Administrative Board proceedings, contemporaneous campus reporting — shows the disciplinary facts but does not support the film's motivational framing. See myth vs. record.

The HarvardConnection approach

While Facemash’s dust settled, three fellow students — twins Cameron and Tyler Winklevoss and Divya Narendra — were building HarvardConnection (later ConnectU), a social network for Harvard students. In late 2003 they approached Zuckerberg about helping with programming. He agreed to help, then — over the following weeks — began building his own project instead. Whether that constituted a betrayal, a misunderstanding, or legitimate parallel work became the founding dispute, litigated for years and settled in 2008. The neutral account is on the myth vs. record page.

thefacebook launches

In January 2004 Zuckerberg began writing what became thefacebook. He launched it on 4 February 2004 from his Kirkland House room. The initial team: Zuckerberg, Dustin Moskovitz (who handled much of the early scaling), Chris Hughes (communications and early outreach), and Eduardo Saverin (early funding and business matters).

The site’s design choices were deliberate and consequential:

Within two weeks, the majority of Harvard undergraduates had registered. Stanford, Columbia, and Yale followed that spring.

Leaving

By the summer of 2004 the team had moved to Palo Alto to work full-time. Zuckerberg did not return to Harvard that fall — effectively dropping out, though he has described the decision as simply following where the work was. In 2017 Harvard awarded him an honorary Doctor of Laws, and he delivered the commencement address, joking that it was the best thing about the day that he had “finally” graduated.
