Josef Mengele (] ; 16 March 19117 February 1979) was a German "Schutzstaffel" (SS) officer and physician in Auschwitz concentration camp during World War II.
 Mengele was a member of the team of doctors responsible for the selection of victims to be killed in the gas chambers and for performing deadly human experiments on prisoners.
 Arrivals deemed able to work were admitted into the camp, and those deemed unfit for labor were immediately killed in the gas chambers.
 Mengele left Auschwitz on 17 January 1945, shortly before the arrival of the liberating Red Army troops.
 After the war, he fled to South America, where he evaded capture for the rest of his life.
Miklos Samual Kanitz (1939–2006) was a Hungarian-Canadian Holocaust survivor living in Saskatoon, Saskatchewan.

Miklós Nyiszli (June 17, 1901, Szilágysomlyó, Austria-Hungary – May 5, 1956, Oradea, Romania) was a Jewish prisoner at the Auschwitz concentration camp.
 Nyiszli, his wife, and young daughter, were transported to Auschwitz in June 1944.
 On arrival, Nyiszli volunteered himself as a doctor and was sent to work at number 12 barracks where he operated on and tried to help the ill with only the most basic medical supplies and tools.
 He was under the supervision of Josef Mengele, an SS officer and physician.
 Mengele decided after observing Nyiszli’s skills to move him to a specially built autopsy and operating theatre.
