Americans Gave the Nazis Eugenics Know-How (12-19-2017, updated 07-11-2017) An article I saw yesterday: "The Nazi Breeding and Infanticide Program You Probably Never Knew About". Yeah, there's a reason you probably never knew about this. 1920s: Hitler's impressed by American eugenics programs. Rich Americans give Germans funds, science and technology for their own programs. 1940: news of atrocities reaches America. 'Eugenics' is never mentioned again in America.
