The San Francisco Bay area was the site of important developments in modern art after World War II. In the late 1940s, when early forms of Abstract Expressionism prevailed in the Bay area, a number of artists—including Elmer Bischoff, Richard Diebenkorn, and David Park—returned to the figure in a consciously naïve style that was expressionist in character. They generated a movement known as Bay Area Figurative Art. It continued in importance into the 1960s with the emergence of a second generation of artists, including Joan Brown. At this time, Diebenkorn evolved an original abstract style out of his figurative paintings. The later art of Diebenkorn was a major contribution to the history of twentieth-century abstraction.
