A special recipient of Rockefeller funding was the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics in Berlin. For decades, American eugenicists had craved twins to advance their research into heredity.
At the time of Rockefeller's endowment, Otmar Freiherr von Verschuer, a hero in American eugenics circles, functioned as a head of the Institute for Anthropology, Human Heredity and Eugenics. Rockefeller funding of that institute continued both directly and through other research conduits during Verschuer's early tenure. In 1935, Verschuer left the institute to form a rival eugenics facility in Frankfurt that was much heralded in the American eugenics press. Research on twins in the Third Reich exploded, backed by government decrees. Verschuer wrote in Der Erbarzt, a eugenics doctor's journal he edited, that Germany's war would yield a "total solution to the Jewish problem."
Verschuer had a longtime assistant. His name was Josef Mengele.
On May 30, 1943, Mengele arrived at Auschwitz. Verschuer notified the German Research Society, "My assistant, Dr. Josef Mengele (M.D., Ph.D.) joined me in this branch of research. He is presently employed as Hauptsturmführer (captain) and camp physician in the Auschwitz concentration camp. Anthropological testing of the most diverse racial groups in this concentration camp is being carried out with permission of the SS Reichsführer (Himmler)."
Mengele began searching the boxcar arrivals for twins. When he found them, he performed beastly experiments, scrupulously wrote up the reports and sent the paperwork back to Verschuer's institute for evaluation. Often, cadavers, eyes and other body parts were also dispatched to Berlin's eugenic institutes.
Rockefeller executives never knew of Mengele. With few exceptions, the foundation had ceased all eugenics studies in Nazi-occupied Europe before the war erupted in 1939. But by that time the die had been cast. The talented men Rockefeller and Carnegie financed, the great institutions they helped found, and the science they helped create took on a scientific momentum of their own.
.....Mengele's boss Verschuer escaped prosecution. Verschuer re- established his connections with California eugenicists who had gone underground and renamed their crusade "human genetics."
Soon, Verschuer again became a respected scientist in Germany and around the world. In 1949, he became a corresponding member of the newly formed American Society of Human Genetics, organized by American eugenicists and geneticists.
In the fall of 1950, the University of Münster offered Verschuer a position at its new Institute of Human Genetics, where he later became a dean. In the early and mid-1950s, Verschuer became an honorary member of numerous prestigious societies, including the Italian Society of Genetics, the Anthropological Society of Vienna, and the Japanese Society for Human Genetics.

Rockefeller spent a great deal of money financing Nazi scientists and eugenic institutions in Germany, among them Otmar Freiherr von Vershuer. Vershuer was particularly interested in twins. With twins you could unlock the mysteries of defective reproduction, they thought, and also with twins you could discover the secret to multiplication of the master race. Vershuer sent his assistant, whose name was Joseph Mengele, into Auschwitz to finish the program originally financed by Rockefeller. But of course, Mengele went there after the war began......Rockefeller was funding the Nazi eugenicists throughout the entire pre-war period. Rockefeller was receiving constant letters of protest because of its open involvement with Nazi medicine......When lawyers and other entities tried to stop me from seeing the records, they even claimed doctor-patient confidentiality for Joseph Mengele!The haunted house of eugenics
