Which Harvard residential house was Mark Zuckerberg living in when he launched Facebook?

Mark Zuckerberg was living in Harvard’s Kirkland House when he launched Facebook.

Zuckerberg launched the site on February 4, 2004, during his sophomore year at Harvard. The first version, called “TheFacebook,” was a Harvard-only online directory where students could create profiles and connect with classmates. Kirkland House was both his residential setting and an important social context for the site’s earliest circulation.

The launch followed an earlier project, Facemash, which had controversially used student photographs for attractiveness rankings. Facemash was shut down, but Zuckerberg’s interest in building campus social software continued. TheFacebook rapidly expanded beyond Harvard and later dropped “The” from its name.

The main mix-up is with other Harvard locations or projects associated with the company’s origin. The Winklevoss brothers and Divya Narendra were connected to the proposed HarvardConnection project, but that does not change Zuckerberg’s residence. Harvard’s own account identifies him as a Kirkland resident in 2004.
