The worst crimes by the Nazi regime were those conducted in the name of science, the human experiments, there were many experiments below are only a few of them.
Experiments on twins
Experiments on twin children in concentration camps were created to show the similarities and differences in the genetics of twins, as well as to see if the human body can be unnaturally manipulated. The central leader of the experiments was Josef Mengele, who from 1943 to 1944 performed experiments on nearly 1,500 sets of imprisoned twins at Auschwitz.
Mengele’s research involved injecting blue dye into children’s eyes and stitching kids together to make sets of conjoined twins. Mystery substances and infectious agents were injected into one twin, then the other twin would be killed within hours of the infected twin’s death so that both could be autopsied at once. In a single year at Auschwitz, Mengele experimented on 3,000 children.
Head injury experiments
In mid-1942 in Baranowicze, occupied Poland, experiments were conducted in a small building behind the private home occupied by a known Nazi SD Security Service officer, in which “a young boy of eleven or twelve was strapped to a chair so he could not move. Above him was a mechanized hammer that every few seconds came down upon his head.” The boy was driven insane from the torture.
Sea water experiments
From about July 1944 to about September 1944, experiments were conducted at the Dachau concentration camp to study various methods of making sea water drinkable.
At one point, a group of roughly 90 Roma were deprived of food and given nothing but sea water to drink by Dr. Hans Eppinger, leaving them gravely injured. They were so dehydrated that others observed them licking freshly mopped floors in an attempt to get drinkable water.
A Holocaust survivor named Joseph Tschofenig wrote a statement on these seawater experiments at Dachau. Tschofenig explained how while working at the medical experimentation stations he gained insight into some of the experiments that were performed on prisoners, namely those where they were forced to drink salt water. Tschofenig also described how victims of the experiments had trouble eating and would desperately seek out any source of water including old floor rags. Tschofenig was responsible for using the X-ray machine in the infirmary and describes how even though he had insight into what was going on he was powerless to stop it. He gives the example of a patient in the infirmary who was sent to the gas chambers by Dr. Sigmund Rascher simply because he witnessed one of the low-pressure experiments.
High altitude experiments
In early 1942, prisoners at Dachau concentration camp were used by Sigmund Rascher in experiments to aid German pilots who had to eject at high altitudes. A low-pressure chamber containing these prisoners was used to simulate conditions at altitudes of up to 20,000 m (66,000 ft). It was rumored that Rascher performed vivisections on the brains of victims who survived the initial experiment. Of the 200 subjects, 80 died outright, and the others were executed.
In a letter from April 5, 1942 between Dr. Sigmund Rascher and Heinrich Himmler, Rascher explains the results of a low-pressure experiment that was performed on people at Dachau Concentration camp in which the victims were suffocated while Rascher and another unnamed doctor took note of his reactions. The person was described as 37 years old and in good health before being murdered. Rascher described the victim’s actions as he began to lose oxygen and times the changes in behavior. The 37 year old began to wiggle his head at 4 minutes, a minute later Rascher observed that he was suffering from cramps before falling unconscious. He describes how the victim then laid unconscious breathing only 3 times per minute until he stopped breathing 30 minutes after being deprived of oxygen. The victim then turned blue and began foaming at the mouth. An autopsy followed an hour later.
In a letter from Heinrich Himmler to Dr. Sigmund Rascher on April 13, 1942, Himmler orders Rascher to continue the high altitude experiments and to continue experimenting on prisoners condemned to death and to “determine whether these men could be recalled to life”. If a victim could be successfully resuscitated, Himmler ordered that he be pardoned to “concentration camp for life.
