Encouraged by von Verschuer, Mengele applied for transfer to the concentration camp service to take advantage of the opportunity to conduct genetic research on human subjects. His application was accepted and he was posted to Auschwitz in the spring of 1943. Mengele first gained notoriety for supervising the selection of arriving prisoners to the camp, determining who would be sent to the gas chambers and who would become a forced laborer. This earned him the reputation as the “Angel of Death.” Whereas most of the other doctors viewed the selection process as one of the most horrible duties and had to get drunk in order to endure it, Mengele had no problem with the task. He often arrived smiling and whistling a tune, and even showed up for selections he wasn’t assigned to.
The St. Louis arrived in Havana harbor on May 27th. Of the 937 passengers on board, only 28 passengers were allowed into Cuba. 22 of these passengers were Jewish and had valid U.S. visas, 4 were Spanish citizens and 2 were Cuban nationals, all with valid documents. This story gained a lot of publicity; it was spread throughout Europe and the United States. The U.S. newspapers reported the story compassionately, but only a handful suggested that the refugees should come to the United States. The United States government decided not to take the steps to permit the passengers into the country.
A memorandum dated July 31, 1941, from Hitler’s top commander Hermann Goering to Reinhard Heydrich, chief of the SD (the security service of the SS), referred to the need for an Endlösung (final solution) to “the Jewish question.” Beginning in September 1941, every person designated as a Jew in German-held territory was marked with a yellow star, making them open targets. Tens of thousands were soon being deported to the Polish ghettoes and German-occupied cities in the USSR.
Dr. Josef Mengele, nicknamed The Angel Of Death, and the other Nazi doctors at the death camps tortured men, women and children and did medical experiments of unspeakable horror during the Holocaust. Victims were put into pressure chambers, tested with drugs, castrated, frozen to death. Children were exposed to experimental surgeries performed without anesthesia, transfusions of blood from one to another, isolation endurance, reaction to various stimuli. The doctors made injections with lethal germs, sex change operations, removal of organs and limbs.
Anne’s diary, a devastating and relatable coming-of-age story, was left behind in the Secret Annex, but kept safe by a family friend, Miep Gies. Anne's father, Otto Frank, was the Secret Annex's sole survivor of the Holocaust. After Otto was liberated from a concentration camp, Miep gave him the diary. Otto Frank edited the diary and removed a few sensitive passages—some that weren’t so nice about Anne’s mom, other Secret Annex members, or parts that seemed too sexual for a teenager in the 1940's. However, the most currently printed versions are more complete.
The Germans began World War II by invading Poland in September 1939. The Nazi leaders then shifted priorities in anti-Jewish policy from expulsion from German-controlled territory to concentration of European Jewish populations in locations suited to future permanent removal. It is not clear that the Nazi leaders were already envisioning mass murder as their "solution" to their so-called Jewish problem.
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.
