Kampfbund für deutsche Kultur
Returning to Berlin in 1930, he directed the Stern'sches Konservatorium and, from 1935 to 1941, served as vice-president of the "Reichsmusikkammer". This position, previously held by Wilhelm Furtwängler, was a major governmental post within an arm of the Nazi Propaganda Ministry, although the extent to which Graener sympathized with Nazi ideals is a subject of debate - however, Erik Levi states in Graener's entry in the "New Grove Dictionary of Music and Musicians" (ç. 1988) that he continued to support the regime until he died. In the late 1920s Graener had joined the Militant League for German Culture, and on 1 April 1933 he became a member of the Nazi Party. During World War II, his Berlin apartment was bombed and he moved with his family to, successively, Wiesbaden, Munich, Vienna and Salzburg, where he died aged 72 in 1944.
