Grace Richardson Clements was an American painter, mosaicist, and art critic. She was active as an artist in the 1920s, 1930s and early 1940s. In 1935, she became involved with a group of artists in Los Angeles known as the Post-Surrealists; other artists in the group included Lorser Feitelson and Helen Lundeberg. With this group, she presented her artwork in a "landmark" exhibition at the San Francisco Museum of Art in December 1935, and then at the Brooklyn Museum the next summer. In addition, she was the first of the group to lay out its theoretical underpinnings, which she did in the March 1936 article "New Content—New Form" in the journal Art Front, published by the American Artists' Congress. She was passionate about social justice and "adopted the theme of social engagement within an essentially Modernist vocabulary". She also created public artworks for the Works Progress Administration.
