The women's concentration camp (Frauenkonzentrationslager or FKL) was established in August 1942, in 15 brick and 15 wooden barracks in sector BIa (Bauabschnitt Ia) in Auschwitz II, when 13,000 women were transferred from Auschwitz I. The camp was later extended into sector BIb, and by October 1943 it held 32,066 women. Conditions in the camp were so poor that, in October 1942, when a group of male prisoners arrived to set up an infirmary, their first task, according to researchers from the Auschwitz museum, was to distinguish the corpses from the women who were still alive. Gisella Perl, a Romanian-Jewish gynecologist and inmate of the women's camp, wrote in 1948:
Some Auschwitz prisoners were subjected to inhumane medical experimentation. The chief perpetrator of this barbaric research was Josef Mengele (1911-79), a German physician who began working at Auschwitz in 1943. Mengele, who came to be known as the “Angel of Death,” performed a range of experiments on detainees. For example, in an effort to study eye color, he injected serum into the eyeballs of dozens of children, causing them excruciating pain. He also injected chloroform into the hearts of twins, to determine if both siblings would die at the same time and in the same manner.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
