The hired hands were earnest and reverent. They began at once to read up on European history, Judaism, and Jewish practice; they consulted a rabbi. They corresponded eagerly with Frank, looking to satisfy his expectations. They travelled to Amsterdam and visited 263 Prinsengracht, the house on the canal where the Franks, the van Daans, and Dussel had been hidden. They met Johannes Kleiman, who, together with Victor Kugler and Miep Gies, had taken over the management of Frank’s business in order to conceal and protect him and his family in the house behind. Reacting to the Hacketts’ lifelong remoteness from Jewish subject matter, Levin took out an ad in the New York Post attacking Bloomgarden and asking that his play be given a hearing. “My work,” he wrote, “has been with the Jewish story. I tried to dramatize the Diary as Anne would have, in her own words. . . . I feel my work has earned the right to be judged by you, the public.” “Ridiculous and laughable,” said Bloomgarden. Appealing to the critic Brooks Atkinson, Levin complained—extravagantly, outrageously—that his play was being “killed by the same arbitrary disregard that brought an end to Anne and six million others.” Frank stopped answering Levin’s letters; many he returned unopened.
The Chelmno killing center begins operation. The Nazis later establish five other such camps: Belzec, Sobibor, Treblinka, Auschwitz-Birkenau (part of the Auschwitz complex), and Majdanek. Victims at Chelmno are killed in gas vans (hermetically sealed trucks with engine exhaust diverted to the interior compartments). The Belzec, Sobibor, and Treblinka camps use carbon monoxide gas generated by stationary engines attached to gas chambers. Auschwitz-Birkenau, the largest of the killing centers, has four large gas chambers using Zyklon B (crystalline hydrogen cyanide) as the killing agent. The gas chambers at Majdanek use both carbon monoxide and Zyklon B. Millions of Jews are killed in the gas chambers in the killing centers as part of the "Final Solution."
Mengele was born on 16 March 1911 to Walburga (née Hupfauer) and Karl Mengele in Günzburg, Bavaria, Germany.[4] He was the oldest of three children; his two younger brothers were Karl Jr. and Alois. Their father was founder of the Karl Mengele & Sons company, producers of farm machinery.[5] Josef was successful at school and developed an interest in music, art, and skiing.[6] He completed high school in April 1930 and went on to study philosophy in Munich,[7] where the headquarters of the Nazi Party were located.[8] In 1931, Mengele joined the Stahlhelm, Bund der Frontsoldaten, a paramilitary organization that was absorbed into the Nazi Sturmabteilung (Storm Detachment; SA) in 1934.[7][9]
