Reinhard Heydrich
In 1922 he joined the Reichsmarine, the German Navy of the Weimar Era. Early in 1931 he was dismissed from the Navy by Admiral Erich Raeder for ungentlemanly behavior, namely breech of promise to marry. He had already met another woman, a Nazi who could get him a job with the Nazi Party. As soon as he was out of the Navy he joined the party and soon joined the SS (led by Heinrich Himmler). Later that year, he married his Nazi girlfriend. He also joined the Gestapo and the Luftwaffe in 1933 when Adolf Hitler came to power.
