The doctors involved were the following: Karl Brandt, Carl Clauberg, August Hirt, Johann Kremer, Maria mandel, Josef Mengele, Herta Oberhauser, and Horst Schumann. In the Bone, Muscle, and Nerve Regeneration and Bone Experiments, sections of bone, muscles, and nerves were removed form the people. The result was agony, mutilation, and permanent disability. During the Dachau High-Altitude Medical Experiments, they put the person into a low-pressure chamber and simulated raised altitude causing death. The Nazi's injected people with different diseases such as jaundice and spotted fever. The result usually was death, if they didn't die the people were in pain. In the Dachau Low-Temperature Medical Experiments, the person was placed in the water in a complete flying uniform with a helmet and life jackets, and they were taken out when the water reached 12 degrees Celcius. The result was fatal when the brain stem and back of the head were chilled. During the Freezing Experiments, the person stays in ice water for 3 hours or were kept naked outside for many hours in temperatures below freezing, resulting in death. In the Incendiary Bomb Experiment, they burned people with phosphorus matter taken from incendiary bombs, resulting in severe pain, suffering, and serious bodily injury. During the Lost (Mustard) Gas Experiments, they deliberately inflicted wounds and infected them with lost. The result was death, pain, and injury. Dr. Josef Mengele, known as the Angel of Death, researched and experimented on twins.
