Mengele worked as a carpenter in Buenos Aires, Argentina, while lodging in a boarding house in the suburb of Vicente López. After a few weeks he moved to the house of a Nazi sympathizer in the more affluent neighborhood of Florida Este. He next worked as a salesman for his family's farm equipment company, Karl Mengele & Sons, and in 1951 he began making frequent trips to Paraguay as regional sales representative. He moved into an apartment in central Buenos Aires in 1953, he used family funds to buy a part interest in a carpentry concern, and he then rented a house in the suburb of Olivos in 1954. Files released by the Argentine government in 1992 indicate that Mengele may have practiced medicine without a license while living in Buenos Aires, including performing abortions.
In 1942, with the Nazis occupying Holland, a thirteen-year-old Jewish girl and her family fled their home in Amsterdam and went into hiding. For the next two years, until their whereabouts were betrayed to the Gestapo, the Franks and another family lived cloistered in the “Secret Annexe” of an old office building. Cut off from the outside world, they faced hunger, boredom, the constant cruelties of living in confined quarters, and the ever-present threat of discovery and death. In her diary Anne Frank recorded vivid impressions of her experiences during this period. By turns thoughtful, moving, and surprisingly humorous, her account offers a fascinating commentary on human courage and frailty and a compelling self-portrait of a sensitive and spirited young woman whose promise was tragically cut short.
The Nazis considered Jews to be the main danger to Germany. Jews were the primary victims of Nazi racism, but other victims included Roma (Gypsies) and people with mental or physical disabilities. The Nazis murdered some 200,000 Roma. And they murdered at least 250,000 mentally or physically disabled patients, mainly German and living in institutions, in the so-called Euthanasia Program.
The Avenue of the Righteous, a place where trees are planted to commemorate rescuers, was inaugurated on Holocaust Remembrance Day 1962. The following year, a commission chaired by a member of Israel's Supreme Court was set up to decide upon criteria for awarding the Righteous Among the Nations. On February 1, Justice Moshe Landau chaired the commission's first meeting.
Mengele sailed to Argentina in July 1949, assisted by a network of former SS members. He initially lived in and around Buenos Aires, then fled to Paraguay in 1959 and Brazil in 1960, while being sought by West Germany, Israel, and Nazi hunters such as Simon Wiesenthal who wanted to bring him to trial. He eluded capture in spite of extradition requests by the West German government and clandestine operations by the Israeli intelligence agency Mossad. He drowned in 1979 after suffering a stroke while swimming off the Brazilian coast, and was buried under a false name. His remains were disinterred and positively identified by forensic examination in 1985.
