Random Horrifying Nazi Experiments Conducted On Humans (21 items)

(#12) Tuberculosis Injections

Experiments were also conducted at the Neuengamme concentration camp. To see if there was the possibility of developing an immunity to tuberculosis, Dr. Kurt Heissmeyer injected tuberculosis bacteria directly into patients' lungs, ending the lives of at least 200 people.

He even conducted this experiment on children, and had 20 children hung to cover up evidence of the experiments from the approaching Allied forces.
(#16) Sterilization Experiments

SS doctors conducted thousands of sterilization experiments on concentration camp prisoners in the 1940s.

These experiments involved the use of surgery, pharmaceuticals, and radiation to discover an inexpensive method to sterilize hundreds of thousands of people.
(#14) Heterochromia Experimentation

Dr. Josef Mengele was obsessed with eye color, specifically heterochromia, a condition in which an individual's irises are more than one color.

During his stay in Auschwitz, Mengele collected the eyes of his deceased victims to provide “research material,” and famously conducted a series of experiments where he added dye to the eye of a patient to see if he could change the color of the iris.
(#11) Sulfonamide Experiments

In the early 1940s at the Ravensbrück female concentration camp, subjects were wounded and then infected with gangrene and tetanus. Their blood circulation was then interrupted by tying off blood vessels at both ends of the wound to create a condition similar to that of a battlefield wound. Infections were further aggravated by forcing various foreign materials like sawdust into the wounds.

The infection was then treated with sulfonamide and other drugs to determine their effectiveness.
(#4) Mass Malaria Experiments

During WWII, over 1,000 prisoners were either bitten by malaria-infected mosquitoes or had extracts from the mucous glands of malaria-infected mosquitoes injected directly into their bloodstream.

Father Leo Miechalowski, who was subjected to the malaria experiments, wrote of the traumatic event, "All of a sudden my heart felt like it was going to be torn out."
(#8) The Jewish Skeleton Collection

In an attempt to create an anthropological display to showcase the alleged inferiority of the "Jewish race," Nazi scientist Ausgust Hirt sanctioned the torture and mutilation of nearly a hundred people. After the victims were exposed to toxic gases, each body was sent to the University of Strasbourg. He would have all organic material removed, leaving only the bones for the skeleton collection.

French soldiers later discovered the collection, which contained unprocessed remains that had their faces obscured to avoid identification.
