German SS and police murdered nearly 2,700,000 Jews in the killing centers either by asphyxiation with poison gas or by shooting. In its entirety, the "Final Solution" called for the murder of all European Jews by gassing, shooting, and other means. Six million Jewish men, women, and children were killed during the Holocaust—two-thirds of the Jews living in Europe before World War II.
Concentration camp crematorium being shown to a US soldier © Organised killing began with the outbreak of war in September 1939, but the first victims were not Jews. The Nazis set about killing people with physical and mental disabilities, whom they regarded as a burden on the state and a threat to the nation's 'racial hygiene'. About 170,000 people were eventually killed under this so-called Euthanasia programme, which also pioneered techniques and employed many of the people later used to kill Jews.
Similar smaller rescue operations occurred in Greece, where Jews were hidden in the mountains or on islands. Later, Greek Jews were smuggled into Turkey. Similar popular aid to the Jews was rendered in Finland and in Holland there was a protest strike in February 1941, against the deportation of Dutch Jews. The Italian army also helped Jews in their occupation zones in France and Yugoslavia, and they played an important role in rescuing Italian Jews before the Germans occupied Italy in September 1943.
People in Tokyo were not united. I felt it silly to deal with them. So, I made up my mind not to wait for their reply. I knew that somebody would surely complain about me in the future. But, I myself thought this would be the right thing to do. There is nothing wrong in saving many people's lives .... The spirit of humanity, philanthropy ... neighborly friendship ... with this spirit, I ventured to do what I did, confronting this most difficult situation ---and because of this reason, I went ahead with redoubled courage. ”
Mengele's eye experiments included attempts to change the eye color by injecting chemicals into the eyes of living subjects, and he killed people with heterochromatic eyes so that the eyes could be removed and sent to Berlin for study. His experiments on dwarfs and people with physical abnormalities included taking physical measurements, drawing blood, extracting healthy teeth, and treatment with unnecessary drugs and X-rays. Many of his victims were dispatched to the gas chambers after about two weeks, and their skeletons sent to Berlin for further analysis. Mengele sought out pregnant women, on whom he would perform experiments before sending them to the gas chambers. Witness Vera Alexander described how he sewed two Romani twins together, back to back, in a crude attempt to create conjoined twins; both children died of gangrene after several days of suffering.
At Auschwitz, Yanina survived the gas chamber when adult bodies fell on top of her, protecting her from inhaling a lethal amount of poison gas. Found moaning by Jewish slave laborers who were forced to remove the bodies from the gas chambers, Yanina was resuscitated, given a uniform and told to blend in. Prisoners under the age of 15 were routinely gassed at Auschwitz, but Yanina was able to escape detection after her remarkable rescue.
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.
