In July 1938, representatives of 32 countries met in the French town of Evian to discuss the refugee and immigration problems created by the Nazis in Germany. Nothing substantial was done or decided at the Evian Conference, and it became apparent to Hitler that no one wanted the Jews and that he would not meet resistance in instituting his Jewish policies. By the autumn of 1941, Europe was in effect sealed to most legal emigration. The Jews were trapped.
A subsidiary aim of Operation Reinhard was to exploit a small minority of Jews residing in the Generalgouvernement as forced laborers before killing them. As the ghettos in Poland were systematically liquidated, those selected to live temporarily were deported to Operation Reinhard labor camps and to the concentration camp Lublin/Majdanek. This camp was established in 1941 under the authority of the Inspectorate of Concentration Camps in Berlin. Though conceived of and functioning in practice primarily as a concentration camp, housing political prisoners and Jewish forced laborers, Majdanek served from time to time as a killing site for Jews residing in the Generalgouvernement. It had gas chambers, in which the SS killed tens of thousands of Jews, primarily forced laborers too weak to work.
Of the eight people in the secret annex, only Otto Frank survived the war. He subsequently returned to Amsterdam, where Gies gave him various documents she had saved from the annex. Among the papers was Anne’s diary, though some of the notebooks were missing, notably most of those from 1943. To fulfill Anne’s dream of publication, Otto began sorting through her writings. The original red-and-white checkered journal became known as the “A” version, while her revised entries, written on loose sheets of paper, were known as the “B” version. The diary that Otto ultimately compiled was the “C” version, which omitted approximately 30 percent of her entries. Much of the excluded text was sexual-related or concerned Anne’s difficulties with her mother.
In May 1960, Isser Harel, director of Mossad (the Israeli intelligence agency), personally led the successful effort to capture Adolf Eichmann in Buenos Aires. He was also hoping to track down Mengele, so that he too could be brought to trial in Israel.[84] Under interrogation, Eichmann provided the address of a boarding house that had been used as a safe house for Nazi fugitives. Surveillance of the house did not reveal Mengele or any members of his family, and the neighborhood postman claimed that although Mengele had recently been receiving letters there under his real name, he had since relocated without leaving a forwarding address. Harel's inquiries at a machine shop where Mengele had been part owner also failed to generate any leads, so he was forced to abandon the search.[85]
The men worked in shifts throughout the night, with saws, files and spoons stolen from the burial pits. Under the cover of darkness, they smuggled wood planks into the lengthening tunnel to serve as struts; as they dug, they brought sandy earth back out and spread it across the bunker floor. Any noise was concealed by the singing of the other prisoners, who were frequently forced to perform for the Sturmbannführer—arias from The Gypsy Baron, by the Austrian composer Johann Strauss II, were a favorite.

As if cold-blooded murder of millions of Jews was not enough, it was done with extreme, perverse cruelty. The victims were packed into cattle trains with standing-room only and without food or water, or heat in the winter, or toilet facilities. Many did not arrive at the camps alive. Those who did arrive at their destination had their heads shaved, with the hair to be used for stuffing mattresses. Stripped of all clothing, most were herded naked into the gas chambers. Dr Johann Kremer, a German SS surgeon, described the gassing of a group of French Jews including 150 boys and girls under the age of 15:
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.[2][3]
