Heinrich Müller, German SS officer (died 1945)

Heinrich Müller was a high-ranking German Schutzstaffel (SS) and police official during the Nazi era. For most of World War II in Europe, he was the chief of the Gestapo, the secret state police of Nazi Germany. Müller was central in the planning and execution of the Holocaust and attended the January 1942 Wannsee Conference, which formalised plans for deportation and genocide of all Jews in German-occupied Europe—the "Final Solution to the Jewish question". He was known as "Gestapo Müller" to distinguish him from another SS general named Heinrich Müller.

The Schutzstaffel was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II.
