Mark Zuckerberg, the founder of Facebook, first met his long-term girlfriend Priscilla Chang while waiting in line for the bathroom at a fraternity party during his sophomore year at Harvard University in 2003.

They began dating back then and have been living together at their home in Palo Alto since 2010.
Priscilla has worked as a science teacher and is now a medical doctor, graduated from Harvard and the UCSF (University of California, San Francisco).
