" The first camp to be discovered in the west was the Natzweiler-Struthof camp in Alsace, which the French army entered on 23 November 1944. Natzweiler-Struthof was one of the principal Nacht und Nebel camps – those institutions that were designed to make suspected Resistance fighters disappear into the ‘night and fog’. Here the French discovered a small gas chamber, where prisoners were hung by their wrists from hooks while Zyklon-B gas was pumped into the room. Many of the victims were destined for the autopsy tables of Strasbourg University, where Dr August Hirt had amassed a collection of Jewish skeletons in order to prove the inferiority of the Jewish race through anatomical study. Others, mostly Gypsies brought here from Auschwitz, were subjected to medical experiments within the camp.21 "
