Höss became a member of the SS on 1 April 1934, when Heinrich Himmler encouraged all Nazi men to join the SS. Höss joined the "SS-Totenkopfverbände" (Death's Head Units) in the same year. He came to admire Himmler so much that he thought whatever Himmler said was "gospel." He even preferred to display Himmler's picture in his office instead of Hitler's.
