Josef Mengele, byname Todesengel (German: “Angel of Death”), (born March 16, 1911, Günzburg, Germany—died February 7, 1979, Enseada da Bertioga, near São Paulo, Brazil), Nazi doctor at Auschwitz extermination camp (1943–45) who selected prisoners for execution in the gas chambers and conducted medical experiments on inmates in pseudoscientific racial studies.
In August 1944, they were discovered and deported to Nazi concentration camps. They were long thought to have been betrayed, although there are indications that their discovery may have been accidental, that the police raid had actually targeted "ration fraud". Of the eight people, only Otto Frank, the oldest, survived the war. Anne died when she was 15 years old in Bergen-Belsen, from typhus. The exact date of her death is unknown, and has long been believed to be in early March, a few weeks before the prisoners were liberated by British troops in April 1945. However, research in 2015 indicated that Anne may have died in February.
Concentration camps began to incarcerate ‘habitual criminals’ in addition to political prisoners. Goebbels stepped up anti-Semitic propaganda with a traveling exhibition which cast Jews as the enemy. Nearly half a million people attended. Some guessed worse would come. Winston Churchill criticised British relations with Germany, warning of ‘great evils of racial and religious intolerance’, though many colleagues complained of his ‘harping on’ about Jews.
Mengele joined the Nazi Party in 1937 and the Schutzstaffel (SS; protection squadron) in 1938. He received basic training in 1938 with the Gebirgsjäger (light infantry mountain troop) and was called up for service in the Wehrmacht (Nazi armed forces) in June 1940, some months after the outbreak of World War II. He soon volunteered for medical service in the Waffen-SS, the combat arm of the SS, where he served with the rank of SS-Untersturmführer (second lieutenant) in a medical reserve battalion until November 1940. He was next assigned to the SS-Rasse- und Siedlungshauptamt (SS Race and Settlement Main Office) in Poznań, evaluating candidates for Germanization.
