Content:  with a particular interest in researching twins. As Von Verschuer's assistant, Mengele focused on the genetic factors that result in a cleft lip and palate, or a cleft chin. His thesis on the subject earned him a cum laude doctorate in medicine (MD) from the University of Frankfurt in 1938. (Both of his degrees were revoked by the issuing universities in the 1960s.) In a letter of recommendation, Von Verschuer praised Mengele's reliability and his ability to verbally present complex material in a clear manner. The American author Robert Jay Lifton notes that Mengele's published works were in keeping with the scientific mainstream of the time, and would probably have been viewed as valid scientific efforts even outside Nazi Germany. On 28 July 1939, Mengele married Irene Schönbein, whom he had met while working as a medical resident in Leipzig. Their only son, Rolf, was born in 1944.

Their father was founder of the Karl Mengele & Sons company (later renamed as Mengele Agrartechnik), which produced farming machinery. Mengele 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 he joined the Der Stahlhelm, a paramilitary organization that was absorbed into the Nazi Sturmabteilung ('Storm Detachment'; SA) in 1934. In 1935, Mengele earned a PhD in anthropology from the University of Munich. In January 1937, he joined the Institute for Hereditary Biology and Racial Hygiene in Frankfurt, where he worked for Otmar Freiherr von Verschuer, a German

Content:  Josef Mengele (16 March 1911 – 7 February 1979), also known as the Angel of Death (Todesengel), was a German Schutzstaffel (SS) officer and physician during World War II. He is mainly remembered for his actions at the Auschwitz concentration camp, where he performed deadly experiments on prisoners, was a member of the team of doctors who selected victims to be killed in the gas chambers and was one of the doctors who administered the gas. With Red Army troops sweeping through German-occupied Poland, Mengele was transferred 280 km from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, ten days before the arrival of the

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 experiments focused primarily on twins, with no regard for the health or safety of the victims. After the war, Mengele fled to South America. He sailed to Argentina in July 1949,

Title: Benno Mengele
Content:  Benno Mengele (11 December 1898 in Zwettl, Lower Austria – 15 September 1971 in Vienna) was an Austrian electrical engineer. Mengele studied from 1918 to 1923 at the Vienna University of Technology and worked from 1922 at the Austrian Siemens-Schuckert. He developed protective earthing and fault current, and in 1929, he and Gustav Markt developed the overhead power line (bundle conductors) for high-voltage and ultrahigh-voltage power transmission. He also built the first hydrogen-cooled three-phase motor in Austria. In 1965, he was awarded an honorary doctorate from the Vienna University of Technology.
Title: Josef Mengele
Content:  Mengele used Auschwitz as an opportunity to continue his anthropological studies and research into heredity, using inmates for human experimentation. His medical procedures showed no consideration for the victims' health, safety, or physical and emotional suffering. He was particularly interested in identical twins, people with heterochromia iridum (eyes of two different colors), dwarfs, and people with physical abnormalities. A grant was provided by the Deutsche Forschungsgemeinschaft ('German Research Foundation'), at the request of Von Verschuer, who received regular reports and shipments of specimens from Mengele. The grant was used to build a pathology laboratory attached to Crematorium II at Auschwitz II-Birkenau. Miklós Nyiszli, a Hungarian Jewish

Mengele's work also involved carrying out selections, a task that he chose to perform even when he was not assigned to do so, in the hope of finding subjects for his experiments, with a particular interest in locating sets of twins. In contrast to most of the other SS doctors, who viewed selections as one of their most stressful and unpleasant duties, he undertook the task with a flamboyant air, often smiling or whistling a tune. He was one of the SS doctors responsible for supervising the administration of Zyklon B, the cyanide-a based pesticide that was used for the mass killings in the Birkenau
