Mark Zuckerberg and Priscilla Chan

Of course, today, nearly everyone knows the story of Facebook CEO Mark Zuckerberg and wife Priscilla Chan. After all, it’s in the hit film The Social Network! “He was this nerdy guy who was just a little bit out there,” Chan told The New Yorker recently. “I remember he had these beer glasses that said ‘pound include beer dot H.’ It’s a bag for C++. It’s like college humor but with a nerdy, computer-science appeal.”

Back in 2012, Zuckerberg tied the knot with his college sweetheart at a surprise marriage ceremony in their Palo Alto backyard. While her husband runs Facebook, Chan is a philanthropist and still-working pediatrician.
