Nearly 1,200 glittering guests feted the San Francisco Museum of Modern Art's first seventy-five years on Friday. The art museum hosted 550 gallerists, museum directors, artists and art collectors at a $50,000-a-table private dinner and several hundred more patrons came for the late night afterparty.

Beleaguered billionaire Mark Zuckerberg, 26, whose Facebook is under fire for privacy issues, arrived dressed in a zipped hoodie. He joined luminaries such as Speaker Nancy Pelosi;  the new director of the Los Angeles Museum of Contemporary Art, Jeffrey Deitch; and former Secretary of State George Shultz whose wife, Charlotte, is a SFMOMA Trustee.

The family of Gap retail founders Doris and the late Don Fisher were well-represented. The Fisher family has leased 1,100 artworks to SFMOMA for which the museum is building a new wing.
