Mark Zuckerberg and Priscilla Chan
Facebook founder and chief executive Mark Zuckerberg and doctor Priscilla Chan were wed in Palo Alto, Calif., on May 19. Wedding guests thought they were attending a graduation party for Chan, who had recently completed medical school at the University of California at San Francisco. But the guests, fewer than 100, were surprised by a ceremony conducted in the back yard of the couple’s home. Zuckerberg updated his status to "married" on Saturday.
