MoMA, the Museum of Modern Art, is a Midtown Manhattan museum established on November 7, 1929, by Abby Aldrich Rockefeller, Lillie P. Bliss, and Mary Quinn Sullivan, opening nine days after the Wall Street Crash. Its collection spans the late nineteenth century to the present and includes more than 200,000 works of painting, sculpture, drawing, photography, architecture, design, and film, organized across six curatorial departments. Under founding director Alfred H. Barr Jr., MoMA pioneered dedicated museum departments for photography and film and mounted landmark exhibitions such as Cubism and Abstract Art in 1936 and a major Picasso retrospective in 1939-40, establishing itself as one of the most influential institutions in the history of modern art. MoMA also operates MoMA PS1 and partners with the Studio Museum in Harlem.
