From the left, composer Richard Strauss, President of the Reichsmusikkammer (Department of Music in the propaganda Ministry); Heinz Drewes, Generalintendant und Generalmusikdirektor (Director/Conductor) of the Reichsmusikkammer; and Joseph Goebbels, the Nazi propaganda chief and President of the Reichskulturkammer (Photograph taken in Berlin in the 1930s).
Strauss resigned his position in July 1935 and was succeeded by Peter Raabe who served as President from 1935 until the end of the war. For much of his tenure, Raabe was not sole leader regarding musical culture in the Reich as in 1936 Goebbels appointed Dr. Heinz Drewes, then Generalmusikdirektor of Altenburg, to head a department of music in the Propaganda Ministry. The entangled roles of Drewes and Raabe in the Reichsmusikkammer and Propaganda Ministry are discussed by Michael Kater in his book:The Twisted Muse: Musicians and Their Music in the Third Reich (read an on line excerpt).
