Rudolph Weisenborn (American, b.1881), 'Geometric Abstraction', c. 1955; oil/canvas, 22.5in. x 30.5in. signed and dated. Important Chicago modernist. He exhibited at the Federal Art Project and the Art Institute of Chicago in 1938. Weisenborn combined references to Cubism, Expressionism, and Fauvism in a highly geometric form of painting. He was a leading figure in the avant-garde art groups, Cor Ardens, Neo-Arlemusc, and Les XX. These groups were reactionary to the conservatism of the Art Institute. He turned primarily to non- objective works in the 1930s, and was a member of the Abstract American Artists.
