From about August 1942 to about May 1943 experiments were conducted at the Dachau concentration camp, primarily for the benefit of the German Air Force, to investigate the most effective means of treating persons who had been severely chilled or frozen. In one series of experiments the subjects were forced to remain in a tank of ice water for periods up to 3 hours. Extreme rigor developed in a short time. Numerous victims died in the course of these experiments. After the survivors were severely chilled, rewarming was attempted by various means.
In another series of experiments, the subjects were kept naked outdoors for many hours at temperatures below freezing. The victims screamed with pain as their bodies froze. The defendants Karl Brand, Handloser, Schroeder, Gebhardt, Rudolf Brandt, Mrugowsky, Poppendick, Sievers, Becker-Freyseng, and Weltz are charged with special responsibility for and participation in these crimes.
