Alongside Bertolt Brecht, the director and theater manager Erwin Piscator (1893-1966) was one of the most influential advocates of political theater in Germany. His experiences on the Western Front in World War I had made him a pacifist, and after the November Revolution he joined the German Communist Party (KPD). From 1927, Piscator ran his own theater in Berlin, which broke new ground, particularly through modern and elaborate stage technology such as film and image projections. Two years later, he published his book, The Political Theater, which documented his most important productions and explained his understanding of theater as an artistic medium “in the incipient process of intellectual revolution.” Piscator worked with numerous artists of the Weimar avant-garde in his productions. The cover of his book was designed by the artist and Bauhaus teacher László Moholy-Nagy (1895-1946), who also designed sets for the Piscator stage.
