Reinhard Tristan Eugen Heydrich (German:[ˈʁaɪnhaʁt ˈtʁɪstan ˈɔʏɡn̩ ˈhaɪdʁɪç] (File:Speaker Icon.svg listen)) (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 (General) and General der Polizei, chief of the Reich Main Security Office (including the Gestapo and Kripo) and Stellvertretender Reichsprotektor (Deputy Reich-Protector) of Bohemia and Moravia (in what is now known as the Czech Republic). Heydrich served as President of Interpol (the international law enforcement agency) and chaired the January 1942 Wannsee Conference, which formalised plans for the final solution to the Jewish Question—the deportation and extermination of all Jews in German-occupied territory.
