In October 1939 Hitler signed a "euthanasia decree" backdated to 1 September 1939 that authorized Reichsleiter Philipp Bouhler, the chief of Hitler's Chancellery, and Karl Brandt, Hitler's personal physician, to carry out a program of involuntary "euthanasia"; after the war this program was named Aktion T4. It was named after Tiergartenstraße 4, the address of a villa in the Berlin borough of Tiergarten, where the various organizations involved were headquartered. T4 was mainly directed at adults, but the "euthanasia" of children was also carried out. Between 1939 and 1941, 80,000 to 100,000 mentally ill adults in institutions were killed, as were 5,000 children and 1,000 Jews, also in institutions. In addition there were specialized killing centres, where the deaths were estimated at 20,000, according to Georg Renno, the deputy director of Schloss Hartheim, one of the "euthanasia" centers, or 400,000, according to Frank Zeireis, the commandant of the Mauthausen concentration camp. Overall, the number of mentally and physically handicapped murdered was about 150,000.
Mengele's name was mentioned several times during the Nuremberg trials in the mid-1940s, but the Allied forces believed that he was probably already dead. Irene Mengele and the family in Günzburg also alleged that he had died. Working in West Germany, Nazi hunters Simon Wiesenthal and Hermann Langbein collected information from witnesses about Mengele's wartime activities. In a search of the public records, Langbein discovered Mengele's divorce papers, which listed an address in Buenos Aires. He and Wiesenthal pressured the West German authorities into starting extradition proceedings, and an arrest warrant was drawn up on 5 June 1959. Argentina initially refused the extradition request because the fugitive was no longer living at the address given on the documents; by the time extradition was approved on 30 June, Mengele had already fled to Paraguay and was living on a farm near the Argentine border.
The capture and trial of Eichmann — and his execution — were enough to teach the world about the Holocaust and to convey the message that Jewish blood cannot be spilled with impunity. From that point on, it would have been better if the Mossad had let the past go. Nazis no longer posed a threat. And there is no lack of present-day enemies who did and apparently always will.

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.
