The Nuremberg trials were a series of military tribunals, held by the Allied forces after World War II in Nuremberg, Germany, to prosecute prominent members of the political, military, and economic leadership of Nazi Germany. The first of these trials was the 1945–1946 trial of the major war criminals before the International Military Tribunal (IMT).[456] This tribunal tried 22 political and military leaders of the Third Reich,[457] except for Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, all of whom had committed suicide several months before.[456]
Mengele's research subjects were better fed and housed than the other prisoners, and temporarily spared from execution in the gas chambers.[42] He established a kindergarten for children who were the subjects of his experiments, as well as the preschool children from the Romani camp. The facility provided better food and living conditions than other areas of the camp, and included a children's playground.[43] When visiting his young subjects, he introduced himself as "Uncle Mengele" and offered them sweets,[44] while at the same time being personally responsible for the deaths of an unknown number of victims whom he killed via lethal injection, shootings, beatings, and his deadly experiments.[45] In his 1986 book, Lifton describes Mengele as sadistic, lacking empathy, and extremely antisemitic, believing the Jews should be eliminated entirely as an inferior and dangerous race.[46] Rolf Mengele later claimed that his father had shown no remorse for his wartime activities.[47]
The Holocaust, also known as the Shoah,[b] was a genocide during World War II in which Nazi Germany, aided by local collaborators, systematically murdered some six million European Jews—around two-thirds of the Jewish population of Europe—between 1941 and 1945.[a][c] Jews were targeted for extermination as part of a larger event during the Holocaust era, in which Germany and its collaborators persecuted and murdered other groups, including Slavs (chiefly ethnic Poles, Soviet prisoners of war, and Soviet citizens), the Roma, the "incurably sick", political and religious dissenters such as communists and Jehovah's Witnesses, and gay men.[d] Taking into account all the victims of Nazi persecution, the death toll rises to over 17 million.[3]
"He grabbed my arm and turned me around," said Freund, now 82. "I was skinny, already. Thank God I didn't have a pimple on my body, because a pimple was all you needed to be sent to the crematorium." (The gas chambers at Auschwitz were located in the crematorium buildings, so that the bodies could be burned immediately after the victims were gassed.)
The superior race was the "Aryans," the Germans. The word Aryan, "derived from the study of linguistics, which started in the eighteenth century and at some point determined that the Indo-Germanic (also known as Aryan) languages were superior in their structures, variety, and vocabulary to the Semitic languages that had evolved in the Near East. This judgment led to a certain conjecture about the character of the peoples who spoke these languages; the conclusion was that the 'Aryan' peoples were likewise superior to the 'Semitic' ones" (Leni Yahil, The Holocaust: The Fate of European Jewry, New York: Oxford University Press, 1990, p. 36).

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.
