Aside from the Eugenics Record Office set up at Cold Spring Harbor on Long Island, the movement would train and send case workers around the country to take family pedigrees and compile data used to argue who had good breeding or not and who deserved the right to reproduce or not. They set up exhibits at county fairs for “public education” on eugenic matters. They would even sponsor something called “Better Baby” and “Fitter Family” contests at these fairs to judge “human stock” the way other organizations attending county fairs judged other things like prize pigs and heirloom tomatoes.
…Again, eugenics didn’t end when it fell out of favor because of the Nazis during World War II; it was simply forced to go underground. It got renamed and buried in more benign scientific sounding areas, like genetics, human ecology, and bioethics. The Rockefeller Foundation and other elite family foundations quietly continued their quest for population control of the general “riff raff” through different means.
