By 1937, the concept of degeneracy was firmly entrenched in Nazi policy. On June 30 of that year Goebbels put Adolf Ziegler, the head of (Reich Chamber of Visual Art), in charge of a six-man commission authorized to confiscate from museums and art collections throughout the Reich, any remaining art deemed modern, degenerate, or subversive. These works were then to be presented to the public in an exhibit intended to incite further revulsion against the "perverse Jewish spirit" penetrating German culture.
