退廃芸術
On 31 March 1933, following the National Socialist rise to power, Baumeister was dismissed from his professorship at the Städel. His colleague Professor Albert Windisch and Wilhelm Biering continued his lessons. Thereafter Baumeister earned his living mainly from commercial art, he was still however able to travel to Switzerland, Italy, and France. In the same year, his daughter Felicitas was born. In 1936 he was introduced by the Wuppertaler architect Heinz Rasch, with whom he work during the 1924 Exhibition in Stuttgart, to Dr. Kurt Herberts, the owner of a varnish factory in Wuppertal. He began working for the company in 1937, joining other artists ostracized by the National Socialist regime: Franz Krause, Alfred Lörcher, Georg Muche, and Oskar Schlemmer, and the art historian Hans Hildebrandt. That year five of his works were shown in the National Socialist exhibition "Entartete Kunst" (Degenerate art) in Munich.
