A sampling of Wilson’s concerns as she matured appears in the interstices of her exchanges with Otto Frank, which, remarkably, date from 1959 until his death, in 1980. For instance: “The year was 1968—etched in my mind. I can’t ever forget it. Otis Redding was ‘Sittin’ on the Dock of the Bay’ . . . while we hummed along to ‘Hey Jude’ by the Beatles.” “In 1973-74,” she reports, “I was wearing headbands, pukka-shell necklaces, and American Indian anything. Tattoos were a rage”—but enough. Tattoos were the rage, she neglects to recall, in Auschwitz; and of the Auschwitz survivor who was her patient correspondent for more than two decades, Wilson remarks, “Well, what choice did the poor man have? Whenever an attack of ‘I-can’t-take-this-any-longer’ would hit me, I’d put it all into lengthy diatribes to my distant guru, Otto Frank.”
The most notorious physician was Josef Mengele, an SS officer who became the Auschwitz camp doctor on 30 May 1943. Interested in genetics and keen to experiment on twins, he would pick out subjects from the new arrivals during "selection" on the ramp, shouting "Zwillinge heraus!" (twins step forward!). They would be measured, killed, and dissected. One of Mengele's assistants said in 1946 that he was told to send organs of interest to the directors of the "Anthropological Institute in Berlin-Dahlem". This is thought to refer to Mengele's academic supervisor, Otmar Freiherr von Verschuer , director from October 1942 of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics in Berlin-Dahlem.[i] Mengele's experiments included placing subjects in pressure chambers, testing drugs on them, freezing them, attempting to change their eye color by injecting chemicals into children's eyes, and amputations and other surgeries.
While there were only 23 main camps between 1933 to 1945, the Nazi regime established some 20,000 other camps used for forced labor, transit or temporary internment. During the Holocaust it is estimated that 6 million Jews were slaughtered along with, 3 million Soviet prisoners of war, 3 million Polish Catholics, 700,000 Serbians, 250,000 Gypsies, Sinti, and Lalleri, 80,000 Germans (for political reasons), 70,000 German handicapped, 12,000 homosexuals, and 2,500 Jehovah’s Witnesses.
In Germany, the Nazis had been murdering mentally and physically disabled people as part of its euthanasia programme since 1939. In the beginning, doctors killed them by lethal injection. This was not considered fast enough, so they developed a new process of gassing that was faster and more effective in killing large numbers of people. Over 70,000 people were killed as part of the euthanasia programme.
In June 1941, Mengele was posted to Ukraine, where he was awarded the Iron Cross 2nd Class. In January 1942, he joined the 5th SS Panzer Division Wiking as a battalion medical officer. After rescuing two German soldiers from a burning tank, he was decorated with the Iron Cross 1st Class, the Wound Badge in Black, and the Medal for the Care of the German People. He was declared unfit for further active service in mid-1942, when he was seriously wounded in action near Rostov-on-Don. Following his recovery, he was transferred to the headquarters of the SS Race and Settlement Main Office in Berlin, at which point he resumed his association with von Verschuer, who was now director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmführer (captain) in April 1943.
