Answer:
Reinhard Heydrich ordered the immediate annihilation of Jews and Communist officials in the conquered Soviet territories; he headed the Gestapo, directed the concentration of Polish Jews into ghettos, and convened the notorious Wannsee conference to announce the Final Solution. He had his hand in every significant anti-Jewish action in Nazi Europe until his assassination by Czech resistance fighters in June 1942. Had he survived that attack, he would in all likelihood have continued to pilot the Nazi destruction of European Jewry to the bitter end
