When an outbreak of noma (a gangrenous bacterial disease of the mouth and face) struck the Romani camp in 1943, Mengele initiated a study to determine the cause of the disease and develop a treatment. He enlisted the assistance of prisoner Dr. Berthold Epstein, a Jewish pediatrician and professor at Prague University. The patients were isolated in a separate barracks and several afflicted children were killed so that their preserved heads and organs could be sent to the SS Medical Academy in Graz and other facilities for study. This research was still ongoing when the Romani camp was liquidated and its remaining occupants killed in 1944.
Josef Mengele (/ˈmɛŋɡələ/; German: [ˈmɛŋələ]; 16 March 1911 – 7 February 1979) was a German Schutzstaffel (SS) officer and physician in Auschwitz concentration camp during World War II. He performed deadly human experiments on prisoners and was a member of the team of doctors who selected victims to be killed in the gas chambers. Arrivals that were judged able to work were admitted into the camp, while those deemed unsuitable for labor were sent to the gas chambers to be killed. With Red Army troops sweeping through Poland, Mengele was transferred 280 kilometers (170 mi) from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, just ten days before the arrival of the Soviet forces at Auschwitz. After the war, he fled to South America where he evaded capture for the rest of his life.
