Wiki. Josef Mengele ; 16 March 1911 7 Feb.1979), often dubbed the "Angel of Death" (German: Todesengel), was a German military officer and physician during World War II at the Soviet front and then at Auschwitz during the Holocaust.[2]
He conducted research and experiments on prisoners at the Auschwitz II-Birkenau concentration camp, where he was a member of the team of doctors who selected victims to be murdered in the gas chambers.[a]..
.. Twin research was of particular interest to Mengele. One twin could serve as a subject with the other as the control.[61]
Mengele viewed the opportunity to undertake twin research at Auschwitz as unique, as it is normally difficult to locate and study a significant number of subjects.[62] The research was conducted on behalf of the Kaiser Wilhelm Institute of Anthropology and the German Research Foundation.[63] Most of the twins he studied were children between the ages of two and sixteen. Historian Nikolaus Wachsmann estimates Mengele may have studied as many as a thousand sets of twins.
Some were siblings who passed themselves off as twins to avoid being killed.[64]
The research largely involved taking dozens of physical measurements and recording the characteristics of various anatomical features. Each examination could take several hours.[65] Mengele generally ordered the twins to undertake weekly physical examinations.[66] Nyiszli and others suggested that twin studies may have been pursued to uncover strategies for 'racially desirable' Germans to produce more twins.[67][56] The actual purpose of Mengele's twin research is unknown.[68]
In his 1945 deposition, Nyiszli testified that he watched Mengele kill 14 twins in a single night, first by injecting evipan to induce sleep, and then by injecting their hearts with chloroform.[44] Nyiszli described it differently in his book; there, he said that he smelled chloroform in the hearts of twins he dissected. He added that he feared Mengele might have him killed for knowing this secret.[69]... More,
