Who Founded Facebook? A New Claim Emerges

Aaron J. Greenspan says he was actually the one who created the original college social networking system, before either side in the legal dispute. And he has the e-mail messages to show it.

As a Harvard student in 2003 — six months before Facebook started and eight months before ConnectU went online — Mr. Greenspan established a simple Web service that he called houseSYSTEM. It was used by several thousand Harvard students for a variety of online college-related tasks. Mr. Zuckerberg was briefly an early participant.
