During World War II, Nazi doctors conducted as many as 30 different types of experiments on concentration-camp inmates. They performed these studies without the consent of the victims, who suffered indescribable pain, mutilation, permanent disability, or in many cases death as a result. At the Nuremberg "doctor's trial," which brought 23 German doctors to trial immediately after the war, prosecutors found 15 defendants guilty of war crimes and crimes against humanity; seven were hung. Here are some of the most notorious experiments:
High altitude
Freezing
Sulfanilamide
Twins
Poison
Tuberculosis
Phosgene
Bone, muscle, and joint transplantation
Sterilization
Artificial insemination
Seawater
