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.
Mengele joined the Nazi Party in 1937 and the Schutzstaffel (SS; protection squadron) in 1938. He received basic training in 1938 with the Gebirgsjäger (light infantry mountain troop) and was called up for service in the Wehrmacht (Nazi armed forces) in June 1940, some months after the outbreak of World War II. He soon volunteered for medical service in the Waffen-SS, the combat arm of the SS, where he served with the rank of SS-Untersturmführer (second lieutenant) in a medical reserve battalion until November 1940. He was next assigned to the SS-Rasse- und Siedlungshauptamt (SS Race and Settlement Main Office) in Poznań, evaluating candidates for Germanization.[18][19]
^ After the invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory.[147][148][149] Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation.[150] Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April.[151] By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau.[152] Resettlement continued until January 1941 under Odilo Globocnik,[153] and included both Jews and Poles.[154] By that time 95,000 Jews were already concentrated in the area,[155] but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.[156]
Von Verschuer’s work revolved around hereditary influences on congenital defects such as cleft palate. Mengele was an enthusiastic assistant to von Verschuer, and he left the lab in 1938 with both a glowing recommendation and a second doctorate in medicine. For his dissertation topic, Mengele wrote about racial influences on the formation of the lower jaw.
Mengele joined the Nazi Party in 1937. He received his medical degree in 1938, the same year he joined the SS. Mengele was drafted into the army in June 1940, and subsequently volunteered for the medical service of the Waffen-SS (Armed SS). There is little (and often contradictory) documentation about Mengele's activities between this time and early 1943. It is clear, however, that he first functioned as a medical expert for the Race and Settlement Main Office in summer 1940 at the Central Immigration Office North-East in Posen (today Poznan). He then served as a medical officer with the SS Division “Wiking” (SS Pioneer Battalion V), with which he saw action on the Eastern Front.
The first transcription of Anne's diary was in German, made by Otto Frank for his friends and relatives in Switzerland, who convinced him to send it for publication.[23] The second, a composition of Anne Frank's versions A and B as well as excerpts from her essays became the first draft submitted for publication, with an epilogue written by a family friend explaining the fate of its author. In the spring of 1946, it came to the attention of Dr. Jan Romein and his wife Annie Romein-Verschoor, two Dutch historians. They were so moved by it that Anne Romein made unsuccessful attempts to find a publisher, which led Romein to write an article for the newspaper Het Parool:[24]
Mengele's health had been steadily deteriorating since 1972. He suffered a stroke in 1976,[99] and he also had high blood pressure and an ear infection that affected his balance. On 7 February 1979, while visiting his friends Wolfram and Liselotte Bossert in the coastal resort of Bertioga, he suffered another stroke while swimming and drowned.[100] Mengele was buried in Embu das Artes under the name "Wolfgang Gerhard", whose identification he had been using since 1971.[101]

He inspired Anne: she planned after the war to publish a book about her time in hiding. She also came up with a title: Het Achterhuis, or The Secret Annex. She started working on this project on 20 May 1944. Anne rewrote a large part of her diary, omitted some texts and added many new ones. She wrote the new texts on separate sheets of paper. She describes the period from 12 June 1942 to 29 March 1944. Anne worked hard: in a those few months, she wrote around 50,000 words, filling more than 215 sheets of paper.
The Jews of Kiev were rounded up by the Einsatzgruppen for “resettlement” in late September 1941. Thousands of Jews were brought to a ravine on the outskirts of Kiev and mowed down by machine guns. Many who were not wounded, including thousands of children, were thrown into the pit of bodies and were buried alive. According to an account in The Holocaust by Martin Gilbert, Ukrainian militia men joined in the slaughter. The records of the Einsatzgruppen unit which participated in the executions recorded 33,771 Jews killed at Babi Yar on September 29-30. In all, more than 100,000 persons, most of them Jews, were executed at Babi Yar between 1941-1943 by the Nazis. In the summer of 1943, the bodies were dug out by slave labor and burned to hide the evidence of the slaughter.

Begin thought settling the score with Mengele would show Palestinian leaders (and the Israeli public) that they would have to pay a price for harming Israelis. His attitude was reflected in a message he sent to President Ronald Reagan when he sent the Israeli Army into Lebanon in 1982, saying that he felt as if “I have sent an army to Berlin to wipe out Hitler in the bunker.”

Mengele's research subjects were better fed and housed than the other prisoners, and temporarily spared from execution in the gas chambers.[42] He established a kindergarten for children who were the subjects of his experiments, as well as the preschool children from the Romani camp. The facility provided better food and living conditions than other areas of the camp, and included a children's playground.[43] When visiting his young subjects, he introduced himself as "Uncle Mengele" and offered them sweets,[44] while at the same time being personally responsible for the deaths of an unknown number of victims whom he killed via lethal injection, shootings, beatings, and his deadly experiments.[45] In his 1986 book, Lifton describes Mengele as sadistic, lacking empathy, and extremely antisemitic, believing the Jews should be eliminated entirely as an inferior and dangerous race.[46] Rolf Mengele later claimed that his father had shown no remorse for his wartime activities.[47]
The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people.[16] Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.[17]
