Dr. Karski was the contact between the Polish resistance and the Polish government in exile. He repeatedly crossed enemy lines to act as a courier between his occupied nation and the West. Prior to his last departure from Poland, he was smuggled into the Warsaw Ghetto by the Jewish underground in order to witness the horrendous conditions. Asked to tell the story to the rest of the world, he reported on his experience to many world leaders, including American President Franklin Roosevelt.
Mengele’s crimes had been well documented before the International Military Tribunal (IMT) and other postwar courts. West German authorities issued a warrant for his arrest in 1959, and a request for extradition in 1960. Alarmed by the capture of Adolf Eichmann in Buenos Aires in that same year, Mengele moved to Paraguay and then to Brazil. He spent the last years of his life near Sao Pãolo. In declining health, Mengele suffered a stroke and drowned while swimming at a vacation resort near Bertioga, Brazil, on February 7, 1979. He was buried in a suburb of Sao Pãolo under the fictive name “Wolfgang Gerhard.”
In 1950, the Dutch translator Rosey E. Pool made a first translation of the Diary, which was never published.[26] At the end of 1950, another translator was found to produce an English-language version. Barbara Mooyaart-Doubleday was contracted by Vallentine Mitchell in England, and by the end of the following year, her translation was submitted, now including the deleted passages at Otto Frank's request. As well, Judith Jones, while working for the publisher Doubleday, read and recommended the Diary, pulling it out of the rejection pile.[27] Jones recalled that she came across Frank's work in a slush pile of material that had been rejected by other publishers; she was struck by a photograph of the girl on the cover of an advance copy of the French edition. "I read it all day", she noted. "When my boss returned, I told him, 'We have to publish this book.' He said, 'What? That book by that kid?'" She brought the diary to the attention of Doubleday's New York office. "I made the book quite important because I was so taken with it, and I felt it would have a real market in America. It's one of those seminal books that will never be forgotten", Jones said.[28] The book appeared in the United States and in the United Kingdom in 1952, becoming a best-seller. The introduction to the English publication was written by Eleanor Roosevelt.

Mengele used Auschwitz as an opportunity to continue his anthropological studies and research into heredity, using inmates for human experimentation.[2] His medical procedures showed no consideration for the health, safety, or physical and emotional suffering of the victims.[2][3] He was particularly interested in identical twins, people with heterochromia iridum (eyes of two different colors), dwarfs, and people with physical abnormalities.[2] A grant was provided by the Deutsche Forschungsgemeinschaft (German Research Foundation), at the request of von Verschuer, who received regular reports and shipments of specimens from Mengele. The grant was used to build a pathology laboratory attached to Crematorium II at Auschwitz II-Birkenau.[38] Dr. Miklós Nyiszli, a Hungarian Jewish pathologist who arrived in Auschwitz on 29 May 1944, performed dissections and prepared specimens for shipment in this laboratory.[39] The twin research was in part intended to prove the supremacy of heredity over environment and thus strengthen the Nazi premise of the superiority of the Aryan race.[40] Nyiszli and others reported that the twin studies may also have been motivated by an intention to increase the reproduction rate of the German race by improving the chances of racially desirable people having twins.[41]
No play can be judged wholly from what is on the page; a play has evocative powers beyond the words. Still, the Hacketts’ work, read today, is very much a conventionally well made Broadway product of the fifties, alternating comical beats with scenes of alarm, a love story with a theft, wisdom with buffoonery. The writing is skilled and mediocre, not unlike much of contemporary commercial theatre. Yet this is the play that electrified audiences everywhere, that became a reverential if robotlike film, and that—far more than the diary—invented the world’s Anne Frank. Was it the play, or was it the times? The upcoming revival of the Hacketts’ dramatization—promising revisions incorporating passages Otto Frank deleted from the diary—will no doubt stimulate all the old quarrelsome issues yet again. But with the Second World War and the Holocaust receding, especially for the young, into distant fable—no different from tales, say, of Attila the Hun—the revival enters an environment psychologically altered from that of the 1955 production. At the same time, Holocaust scholarship survivor memoirs, oral histories, wave after wave of fresh documentation and analysis—has increased prodigiously. At Harvard, for instance, under the rubric “reception studies,” a young scholar named Alex Sagan, a relative of the late astronomer, is examining the ways Anne Frank has been transmuted into, among other cultural manifestations, a heavenly body. And Steven Spielberg’s “Schindler’s List,” about a Nazi industrialist as savior, has left its mark.
AT AUSCHWITZ, on 24th December, 1942, I was paraded in company with about 19,000 other prisoners, all of them women. Present on parade were Doctors Mengele and Konig and Rapportfuhrer Tauber. I was one of the 3000 prisoners picked out of the 19,000 by the doctors and taken to our huts, where we were stripped naked by other prisoners and our clothes taken away. We were then taken by tipper-type lorries to the gas chamber chute. They were large lorries, about eight in all and about 300 persons on each lorry. On arrival at the gas chamber the lorry tipped up and we slid down the chute through some doors into a large room. The room had showers all around, towels and soap and large numbers of benches. There were also small windows high up near the roof. Many were injured coming down the chute and lay where they fell. Those of us who could sat down on the benches provided and immediately afterwards the doors of the room were closed. My eyes then began to water, I started to coughing and had a pain in my chest and throat. Some of the other people fell down and others coughed and foamed at the mouth. After being in the room for about two minutes the door was opened and an S.S. man came in wearing a respirator. He called my name and then pulled me out of the room and quickly shut the door again. When I got outside I saw S.S man Franz Hoessler, whom I identify as No. 1 on photograph 9. He took me to hospital, where I stayed for about six weeks, receiving special treatment from Dr. Mengele. For the first few days I was at the hospital I found it impossible to eat anything without vomiting. I can only think that I was taken out of the gas chamber because I had an Aryan husband and therefore was in a different category from the other prisoners, who were all Jews. I now suffer from a weak heart and had two attacks since being at Belsen. I do not know the names of any persons who went into the gas chamber with me.
Further trials at Nuremberg took place between 1946 and 1949, which tried another 185 defendants.[460] West Germany initially tried few ex-Nazis, but after the 1958 Ulm Einsatzkommando trial, the government set up a governmental agency to investigate crimes.[461] Other trials of Nazis and collaborators took place in Western and Eastern Europe. In 1960, Mossad agents captured Adolf Eichmann in Argentina and brought him to Israel to stand trial on 15 indictments, including war crimes, crimes against humanity, and crimes against the Jewish people. He was convicted in December 1961 and executed in June 1962. Eichmann's trial and death revived interest in war criminals and the Holocaust in general.[462]
It might be noted that, to a surprising extent, much about Hitler’s precise knowledge of the Holocaust remains unclear. For instance, we do not know if Hitler ever saw photographs or newsreels of the killing process, or, indeed, just how comprehensive and brutally frank were Himmler’s reports to Hitler. We have agendas of face-to-face meetings between Hitler and Himmler, at which the Holocaust was to be discussed, but no memorializations or minutes of such meetings. Most of the senior Nazis who were tried at Nuremberg in 1945-1946 (few of whom had any immediate involvement in the killing of Jews) had apparently never seen photographic evidence of the horrors of the concentration camps until their trials; they appeared to be genuinely shocked when newsreels of Belsen and Buchenwald were shown to the court.
These three extermination factories — with Belzec responsible for about 600,000 victims, Sobibor 200,000, Treblinka 900,000 — shared certain features. Like Auschwitz at a later stage, they were equipped with railroad terminals that the trains entered in reverse. The victims were ordered to undress and then led through a corridor to the gas chambers; the gas was composed of carbon monoxide produced by diesel motors. At first, the corpses were buried in mass graves, later they were burnt in crematoria. The similarity to the “euthanasia” program was evident here too. In August 1941, the camps inspector was SS Sturmbannfiihrer Christian Wirth who, like dozens of other specialists of “Operation T4,” was placed under Odilo Globocnik, the commander of the SS for the region of Lublin.
"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.)
Seven months later, November 1943, the U.S. Congress held hearings concerning the U.S. State Department's total inaction regarding the plight of European Jews. President Franklin Roosevelt responded to the mounting political pressure by creating the War Refugee Board (WRB) in January 1944 to aid neutral countries in the rescue of Jews. The WRB helped save about 200,000 Jews from death camps through the heroic efforts of persons such as Swedish diplomat Raoul Wallenberg working tirelessly in occupied countries.
He acted instantly. He sent Otto Frank a copy of “In Search” and in effect offered his services as an unofficial agent to secure British and American publication, asserting his distance from any financial gain; his interest, he said, was purely “one of sympathy.” He saw in the diary the possibility of “a very touching play or film,” and asked Frank’s permission to explore the idea. Frank at first avoided reading Levin’s book, saturated as it was in passions and commitments so foreign to his own susceptibilities. He was not unfamiliar with Levin’s preoccupations; he had seen and liked one of his films. He encouraged Levin to go ahead—though a dramatization, he observed, would perforce “be rather different from the real contents” of the diary. Hardly so, Levin protested: no compromise would be needed; all the diarist’s thoughts could be preserved.
Mengele's work also involved carrying out selections, a task that he chose to perform even when he was not assigned to do so, in the hope of finding subjects for his experiments,[33] with a particular interest in locating sets of twins.[34] In contrast to most of the other SS doctors, who viewed selections as one of their most stressful and unpleasant duties, he undertook the task with a flamboyant air, often smiling or whistling a tune.[35][31] He was also one of the SS doctors responsible for supervising the administration of Zyklon B, the cyanide-based pesticide that was used for the mass killings in the Birkenau gas chambers. He served in this capacity at the gas chambers located in crematoria IV and V.[36]
