Reinhard Tristan Eugen Heydrich (7 March 1904 – 4 June 1942) was a high-ranking German Nazi official during World War II, and one of the main architects of the Holocaust. He was SS-Obergruppenführer und General der Polizei as well as chief of the Reich Main Security Office (including the Gestapo, Kripo, and SD). He was also Stellvertretender Reichsprotektor (Deputy/Acting Reich-Protector) of Bohemia and Moravia, in what is now the Czech Republic. Heydrich served as president of the International Criminal Police Commission (ICPC; later known as Interpol) and chaired the January 1942 Wannsee Conference, which formalised plans for the Final Solution to the Jewish Question—the deportation and genocide of all Jews in German-occupied Europe.
