Bruno Beger was a German racial anthropologist, ethnologist, and explorer who worked for the Ahnenerbe. In that role he participated in Ernst Schäfer's 1938–39 journey to Tibet, helped the Race and Settlement Office, or SS-Rasse- und Siedlungshauptamt, of the SS identify Jews, and later helped select human subjects to be killed to create an anatomical study collection of Jewish skulls.

Natzweiler-Struthof was a Nazi concentration camp located in the Vosges Mountains close to the villages of Natzweiler and Struthof in the Gau Baden-Alsace of Germany, on territory annexed from France on a de facto basis in 1940. It operated from 21 May 1941 to September 1944, and was the only concentration camp established by the Germans in the territory of pre-war France. The camp was located in a heavily-forested and isolated area at an elevation of 800 metres (2,600 ft).
