August Hirt, like many Nazi doctors, is most closely associated with his role in the medical experimentation on and gassings of groups of Jewish prisoners. What makes him unique was motive: instead of seeing the gassing of prisoners as a quick and effective method of extermination, Hirt wanted to significantly expand the skull and skeleton collection for his institute at the University of Strasbourg. He wanted to create a museum of "sub-humans, in which proofs of the degeneracy and the animality of the Jews would be collected."
In an essay at The Holocaust History Project, Anne S. Reamey explains the history of August Hirt. The article can be found at the following link:
