Joseph Wulf was a German-Polish Jewish historian. A survivor of the Auschwitz concentration camp, he was the author of several books about Nazi Germany and the Holocaust, including Das Dritte Reich und die Juden ; Heinrich Himmler (1960); and Martin Bormann: Hitlers Schatten (1962). The House of the Wannsee Conference museum in Berlin houses the Joseph Wulf Library in his honour.

The Wannsee Conference was a meeting of senior government officials of Nazi Germany and Schutzstaffel (SS) leaders, held in the Berlin suburb of Wannsee on 20 January 1942. The purpose of the conference, called by the director of the Reich Security Main Office SS-Obergruppenführer Reinhard Heydrich, was to ensure the co-operation of administrative leaders of various government departments in the implementation of the Final Solution to the Jewish Question, whereby most of the Jews of German-occupied Europe would be deported to occupied Poland and murdered. Conference participants included representatives from several government ministries, including state secretaries from the Foreign Office, the justice, interior, and state ministries, and representatives from the SS. In the course of the meeting, Heydrich outlined how European Jews would be rounded up and sent to extermination camps in the General Government, where they would be killed.
