After only four days of working in Hamburg, Ruth Elias was escorted by an SS man, in a private compartment on a passenger train, to the infirmary at Ravensbrück, the women's concentration camp near Berlin. From there, Ruth and Berta Reich, another prisoner who was nine months pregnant, were soon sent back to Auschwitz on another passenger train. Ruth gave birth to a baby girl at Auschwitz, but Dr. Mengele cruelly ordered her to bind her breasts and not to nurse her child because he wanted to see how long it would take for a baby to die without its mother's milk. Mercifully, a woman dentist named Maca Steinberg, who was a prisoner at Auschwitz, obtained some morphine and gave it to Ruth so that she could inject her baby and end its life, after Ruth told her that Dr. Mengele was due to arrive the next morning to take Ruth and her child to the gas chamber.
Concentration camps were top priority in the conference. ""Nazis would trap Jews in ghettos'' said Himmler. Then they were taken to death camps. Auschwitz mainly. They killed 1 to 3 million people there. '' Under proper guidance in the Final Solution the Jews are to be relocated for appropriate labor in the east. Able-bodied Jews will be separated according to sex. Then taken in large work columns to work on roads of course many will die of natural causes.'' Himmler said this during the conference.
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps. From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II. Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942. Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews. At least 1.4 million of these were in the General Government area of Poland.
Anne’s last diary entry was written on August 1, 1944. Three days later the secret annex was discovered by the Gestapo, which had received a tip from Dutch informers. All of the inhabitants were taken into custody. In September the Frank family arrived at Auschwitz, though Anne and Margot were transferred to Bergen-Belsen the following month. In 1945 Anne as well as her mother and sister died.
Mengele became interested in using twins for medical research through his mentor, Verschuer. Verschuer himself was famous for experimenting with identical and fraternal twins in order to trace the genetic origins of various diseases. During the 1930s, twin research was seen as an ideal tool in weighing the factors of human heredity and environment. Mengele and his mentor had performed a number of legitimate research protocols using twins as test subjects throughout the 1930s. Now, at Auschwitz, with full license to maim or kill his subjects, Mengele performed a broad range of agonizing and often lethal experiments with Jewish and Roma (Gypsy) twins, most of them children.
Mengele was born on 16 March 1911 to Walburga (née Hupfauer) and Karl Mengele in Günzburg, Bavaria, Germany. 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. Josef was successful at school and developed an interest in music, art, and skiing. He completed high school in April 1930 and went on to study philosophy in Munich, where the headquarters of the Nazi Party were located. In 1931, Mengele joined the Stahlhelm, Bund der Frontsoldaten, a paramilitary organization that was absorbed into the Nazi Sturmabteilung (Storm Detachment; SA) in 1934.
