On 28 July 1941, Schumann arrived in
Auschwitz. He worked at Block 30 in the women's hospital, where he set up an X-ray station in 1942. Here men and women were forcibly sterilized by being positioned repeatedly for several minutes between two X-ray machines, the rays aiming at their sexual organs. Most subjects died after great suffering, or were gassed immediately because the radiation burns from which they suffered rendered them unfit for work. Schumann "...chose his test persons himself. They were always young, healthy, good-looking Jewish men, women and girls who looked like old people afterwards. The parts of the body that were treated with the rays experienced severe radiation burns and suppuration (i.e. discharge of pus). Men's testicles and women's ovaries were then surgically removed and sent to
Breslau for histopathological examination. Part of Schumann's control tests, to check whether the radiation had worked, was the so-called semen check: a stick covered with a rubber hose was inserted into the rectum of the victim and the glands stimulated until ejaculation occurred so that the ejaculate could be tested for sperm..." Both kinds of samples were sent to the University of
Breslau (today
Wrocław) for examination. where Schumann committed his medical atrocities Schumann selected some of the women in
Block 10 in the main camp of Auschwitz. In this Block Jewish women had been imprisoned for human experiments. To control the radiation on women, prisoner doctors (Dr. Maximilian Samuel, Dr. Wladislaw Dering) had to remove an ovary. Schumann also performed
typhus experiments by injecting people with blood from typhus patients and then attempting to cure the newly infected subjects. Schumann left Auschwitz in September 1944 and was appointed to the
Sonnenstein Clinic in
Saxony which had earlier been converted into a military hospital. ==Medical career after the war==
