In 1936, the Fine Arts Division of the Reich Chamber of Culture closed what would be the DKB's final exhibition, which he was directing. The following year, forty-three of his works were classified as "degenerate art" and confiscated. Three were shown at the Degenerate Art Exhibition in Munich. A bombing raid in 1943 destroyed his studio and all of his remaining art works. Twenty-two paintings and over one hundred drawings were in the possession of his friend, the art collector , and were saved.
