He began as a law graduate from Leipzig — and became one of the most ruthless SS commanders of the Holocaust. As head of the Gestapo and Security Police in occupied Poland, he led Einsatzgruppen death squads that massacred Jews, Polish elites, and professors in Lwów. A participant at the Wannsee Conference, he enforced the “Final Solution” with fanatic zeal. In 1944, he ordered the execution of captured U.S. pilot Americo S. Galle in the Netherlands. After the war, the British tried him for war crimes. Justice caught up with him at Hamelin Prison in 1946.
