Nazi eugenics
In 1927, The Kaiser Wilhelm Institute for Anthropology (KWIA) was created in Berlin with a lot of financial support from the American philanthropic group, the Rockefeller Foundation. The KWIA's director was Eugen Fischer, a German professor of medicine, anthropology, and eugenics. Fischer said he had found scientific proof of the Nazis' eugenics ideas, and the Nazis used his work to justify their eugenics policies.
