The Korherr Report is a 16-page document on the progress of the Holocaust in German-controlled Europe. It was delivered to Heinrich Himmler in January 1943 by the chief inspector of the statistical bureau of the "SS" and professional statistician Dr Richard Korherr under the title "die Endlösung der Judenfrage", in English the "Final Solution to the Jewish Question". Commissioned by Himmler, Korherr calculated that, from 1937 to December 1942, the number of Jews in Europe had fallen by 4 million. Between October 1939 and December 31, 1942 (see, page 9 of the Report), 1.274 million Jews had been "processed" at the camps of General Government and 145,000 at the camps in "Warthegau" (location of Kulmhof).
