From 1 April 1936 Hirt was associate director of the Institute of anatomy at
University of Greifswald. On 1 October 1938, he obtained the same post at
Goethe University Frankfurt. At the beginning of the
Second World War, he was an SS medical chief (from August 1939 to April 1941). During this time the
Battle of France took place, resulting in the fall of France and its occupation by German forces, and Hirt participated in the battle. He then became director of the new Institute of anatomy at the . from among the
Auschwitz concentration camp inmates in order to create an anatomical specimen collection specifically of Jews. Hirt proposed to use the small-scale gas chamber at Natzweiler-Struthof to murder the people selected, keeping their corpses intact, and then have their corpses shipped immediately to the Anatomical Institute in Strasbourg for the casts and skeletons he wanted for this collection. Hirt directed that 115 persons be selected for measurements: 79 Jewish men, 30 Jewish women, 2 Poles, and 4 "Asians". They were selected among the inmates in August 1943 at Auschwitz by his assistants, the anthropologists Bruno Beger and Hans Fleischhacker. The group was quarantined to protect them from a typhus epidemic in the camp. Measurements were taken of the selected inmates at Auschwitz. Of those initially selected, it is believed that 89 persons (60 men and 29 women) were sent to the
Natzweiler-Struthof concentration camp. Three men died en route, leaving 86 people.
Natzweiler-Struthof camp These 86 people were sent to Natzweiler-Struthof on 30 July 1943. They were fed reasonably well to improve their appearance for the body casts. They were divided into four groups and successively gassed by
Josef Kramer, on 11, 13, 17, and 19 August 1943. Their bodies were returned to Hirt at the anatomical laboratory of the Reich University in Strasbourg for preparation as an
anthropological display, taking body casts and preparing the skeletons. In September 1944, the rapid approach of the Allies led to the project being abandoned and Himmler ordered the destruction of all traces of this compromising collection. That order was not completed, nor had the casts been taken or the skeletons been prepared. The Allies found corpses and partial remains preserved in
formalin for eighty-six bodies upon the liberation of Strasbourg. The corpses were buried 23 October 1945 in the municipal cemetery of Strasbourg-Robertsau before being transferred in 1951 to the Jewish cemetery of Strasbourg-Cronenbourg. The names of the victims were not known, and the purpose for their presence at the Anatomical Institute were not known. Some information was learned in post-war trials as to the project proposed by Hirt. August Hirt fled Strasbourg in September 1944, hiding in
Tübingen in southern Germany across the river from Alsace. ==Death==
