The Warsaw Ghetto Uprising was the largest ghetto revolt. Massive deportations (or Aktions) had been held in the ghetto from July to September 1942, emptying the ghetto of the majority of Jews imprisoned there. When the Germans entered the ghetto again in January 1943 to remove several thousand more, small unorganized groups of Jews attacked them. After four days, the Germans withdrew from the ghetto, having deported far fewer people than they had intended. The Nazis reentered the ghetto on April 19, 1943, the eve of Passover, to evacuate the remaining Jews and close the ghetto. The Jews, using homemade bombs and stolen or bartered weapons, resisted and withstood the Germans for 27 days. They fought from bunkers and sewers and evaded capture until the Germans burned the ghetto building by building. By May 16 the ghetto was in ruins and the uprising crushed.
They were dependent on the general political and military situation. Helping Jews was thus more successful as liberation approached than in the early days of the war. Later in the war, the time required in hiding was shorter, support from local resistance movements was better organized, and the degree of popular hostility to rescue was muted by imminent military defeat.
The United States Holocaust Memorial Museum defines the Holocaust as the "systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators", distinguishing between the Holocaust and the targeting of other groups during "the era of the Holocaust". According to Yad Vashem, Israel's Holocaust memorial, most historians regard the start of the "Holocaust era" as January 1933, when Hitler was named Chancellor of Germany. Other victims of the Holocaust era include those viewed as inferior, including for reasons of race or ethnicity (such as the Roma, ethnic Poles, Russians, and the disabled); and those targeted because of their beliefs or behavior (such as Jehovah's Witnesses, communists, and homosexuals). Hitler came to see the Jews as "uniquely dangerous to Germany", according to Peter Hayes, "and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it". The persecution and murder of other groups was much less consistent. For example, he writes, the Nazis regarded the Slavs as "sub-human", but their treatment consisted of "enslavement and gradual attrition", while "some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—[were] allotted a favored place in Hitler's New Order".
That the designated guru replied, year after year, to embarrassing and shabby effusions like these may open a new pathway into our generally obscure understanding of the character of Otto Frank. His responses—from Basel, where he had settled with his second wife—were consistently attentive, formal, kindly. When Wilson gave birth, he sent her a musical toy, and he faithfully offered a personal word about her excitements as she supplied them: her baby sons, her dance lessons, her husband’s work on commercials, her freelance writing. But his letters were also political and serious. It is good, he wrote in October, 1970, to take “an active part in trying to abolish injustices and all sorts of grievances, but we cannot follow your views regarding the Black Panthers.” And in December, 1973, “As you can imagine, we were highly shocked about the unexpected attack of the Arabs on Israel on Yom Kippur and are now mourning with all those who lost members of their families.” Presumably he knew something about losing a family. Wilson, insouciantly sliding past these faraway matters, was otherwise preoccupied, “finding our little guys sooo much fun.”
Mengele’s father was founder of a company that produced farm machinery, Firma Karl Mengele & Söhne, in the village of Günzburg in Bavaria. Mengele studied philosophy in Munich in the 1920s, coming under the influence of the racial ideology of Alfred Rosenberg, and then took a medical degree at the University of Frankfurt am Main. He enlisted in the Sturmabteilung (SA; “Assault Division”) in 1933. An ardent Nazi, he joined the research staff of a newly founded Institute for Hereditary Biology and Racial Hygiene in 1934. During World War II he served as a medical officer with the Waffen-SS (the “armed” component of the Nazi paramilitary corps) in France and Russia. In 1943 he was appointed by Heinrich Himmler to be chief doctor at Birkenau, the supplementary extermination camp at Auschwitz, where he and his staff selected incoming Jews for labour or extermination and where he supervised medical experiments on inmates to discover means of increasing fertility (to increase the German “race”). His chief interest, however, was research on twins.
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.
