Carl Buchheister (1890 – 1964), was a German constructivist artist noted for his multiple series of "model paintings" which he began in 1925. Though he was not officially part of the Bauhaus movement, Buchheister was a close friend of Wassily Kandinsky and paralleled many of the social and artistic goals of the Bauhaus school. With regard to constructivism, Buchheister was typically more playful and improvisational than his contemporaries, becoming interested in the Dada movement after a collaboration with Kurt Schwitters in the late 1920s which led him to incorporate more varied materials such as plexiglass, aluminum, wood, and twine into his compositions. This direction was given much freer reign after World War II and the end of Nazism.
