Shortly after WWII a complete scientific discipline, eugenics, disappeared under a cloud. At least it seems to have disappeared, together with international journals and world congresses, which obviously never took place.
US Eugenists wrote during the 30s:
The fact that a great state like the German Republic, which for many centuries has helped furnish the best that science has bred, has in its wisdom seen fit to enact a national eugenic legislative act providing for the sterilization of hereditarily defective persons seems to point the way for an eventual worldwide adoption of this idea.”
Some more details:
The university’s reputation led Dr. Harry H. Laughlin, a prominent national eugenicist, to propose Charlottesville to benefactor Wickliffe Draper as home for a national center for eugenics education.
Laughlin knew Virginia. Author of a 1914 model sterilization law for states, he also had corresponded extensively with Plecker about Virginia’s race-purity campaign. He had given testimony in the Carrie Buck legal case and helped to win passage of the Racial Integrity Act.
In 1935, Laughlin’s affinity with Nazi thinking was shown further when he sent a paper on American sterilization law to be read by a like-minded colleague at a World Population Congress in Berlin. The colleague applauded Nazi racial principles and ended his speech with: “To that great leader, Adolf Hitler!”
Draper, the benefactor, was keenly interested in eugenics and attended the same Berlin conference. He also visited Charlottesville, but Laughlin’s 1936 proposal for a national center on eugenics education was not adopted.
In the same year that Laughlin floated the U.Va. idea, he received from Nazi-controlled Heidelberg University an honorary degree for his achievements in the “science of racial cleansing.”
Laughlin wrote back, according to Lombardo, that he found the degree a personal honor and “also evidence of a common understanding of German and American scientists of the nature of eugenics.”
"Eugenics" meaning "harmony in our genetic material" escaped any ethical debate. Instead the image of Nazi Germany being uniquely evil was created.
It is dangerous and unethical for any science to exist with lies or deception about history
That fact alone should make everyone suspicious. Eugenics still exist in many sciences, working "undercover", furtherly escaping ethical control. It will not create "better human races" but further catastrophies, as long as it is kept behaving the way it does.
