Jackson Pollock had his first museum show at SFMOMA, as did Clyfford Still and Arshile Gorky. The museum has in its collection important works by Henri Matisse, Jean Metzinger, Paul Klee, Marcel Duchamp, Andy Warhol, Jackson Pollock, Richard Diebenkorn, Clyfford Still, Dorothea Lange, and Ansel Adams, among others. Annually, the museum hosts more than twenty exhibitions and over three hundred educational programs. While the museum's building was closed for expansion, from summer 2013 through early 2016, SFMOMA presented its exhibitions and programs at off-site locations around the Bay Area as part of SFMOMA On the Go.
