Professor Carl Clauberg (1898-1957) after serving in World War I studied medicine and became the doctor-in-chief to the gynaecological clinic at Kiel University. In 1933 he joined the Nazi party and was a supporter of its ideology. He would also become professor for gynaecology at Koenigsberg University that same year. At Koenigsberg he did research on female fertility hormones and the use for infertility treatments. This got him recognition in 1937 and Himmler was made aware of his work. He also received the rank of SS-Gruppenführer (equivalent of a 2 -star general) in the Reserve.
In 1942 Clauberg asked Heinrich Himmler about doing research on mass sterilization of women. Himmler sent him to Auschwitz in December 1942 where he was given part of Block 10 in the camp to do his experiments. Clauberg was looking at cheap and effective ways to this. He used both Jewish and Romani (Gypsy) women who were often injected without anesthetics in their uterus. Some of the women died from the experiments and others were killed so they could do autopsies. By 1943 he reported to Himmler that he had perfected the procedure. It would require 10 people and well stocked office that could sterilize hundreds up to a 1,000 women per day.
The procedure he used required the injection of a chemical irritant that caused from the resulting inflammation, the growing of the fallopian tubes together causing obstruction. The experiments were brutal and often had complications for the women. Peritonitis and hemorrhages often resulted in high fever and sepsis. Organs failed as well resulting in death. It is believed 700 women were sterilized in these experiments.
He had to flee Auschwitz as the Russian army closed in and ended up in Ravensbruck where he continued his experiments. He was captured by the Russians, put on trial, and sentenced to 25 years in jail. He was released to Germany as part of the 1955 Adenauer-Bulganin prisoner exchange agreement. He ended up back at his old clinic but his bizarre behavior where he bragged about what he did at Auschwitz got him noticed. He was arrested in 1955 after a public outcry but died in 1957 before he stood trial.
