Carl Clauberg was a German physician who was among the many doctors who carried out experiments on the unfortunate inmates of the Nazi concentration camps. He worked in Aushwitz, having got approval from Heinrich Himmler to conduct sterilization experiments on women. He tried to find cheap methods of sterilization, injecting acids in to uterus and all. Around 700 women were subjected to experiments, many of who lost lives. Clauberg was later caught by Soviet forces and released. He was arrested again but he died before going on trial.
