Balcomb Greene (1904–1990) and his wife, artist Gertrude Glass Greene, were heavily involved in political activism to promote mainstream acceptance of abstract art. They were founding members of the American Abstract Artists organization. His early style was completely non-objective. Juan Gris and Piet Mondrian as well as Pablo Picasso and Henri Matisse influenced his early style. From the 1940s his work "opened out to the light and space of natural form." He painted landscapes and figure.
