Eugenics is the science of “good births” which aims to create the perfect human being and tries to achieve this by preventing reproduction of those perceived as weak, sick, disabled, or otherwise “degenerate.” Before being employed by the Nazis in what remains the most deadly program of “racial purification”, eugenics was a very popular concept among scientists in the United States and Europe. As early as 1907, the United States applied the first eugenics laws, which continued to be in force until the 1970s. More than 60,000 people were denied children under widespread campaigns of forced sterilization.
