The charge: they had quietly sterilized her during what was supposed to be a routine appendix removal. The green light for the procedure came from a single word scribbled on a medical form hours before the operation. That word was "feeble-minded." This was not a back-alley scandal cooked up by rogue doctors. It was the tip of a massive thirty-year national movement called eugenics, backed by Harvard scientists, Wall Street millionaires, senators, and even presidents.

Show Notes
In the late nineteenth and early twentieth centuries, a movement known as eugenics gained support in many parts of the world. Advocates believed that society could be improved through selective breeding and policies designed to influence human populations.
What began as a controversial scientific theory soon affected laws, public policy, education, and medicine in numerous countries. Its influence reached governments, universities, and social institutions before its ideas were increasingly challenged and discredited.
A calm journey through scientific ambitions, political movements, social engineering, and one of the most controversial chapters in modern history.
