Robert Foster Kennedy Draws Some Extreme Conclusions

Robert Foster Kennedy was married twice and died in New York in 1952. 

Some of the more controversial views that he held in the latter part of his career are summarised in his Wikipedia entry:

Kennedy supported widespread eugenical sterilization and castration.

At the 1941 annual meeting of the American Psychiatric Association, he called for the extermination of incurably severely retarded children over the age of five. His goal was to relieve "the utterly unfit" and "nature's mistakes" of the "agony of living" and to save their parents and the state the cost of caring for them. He concluded, "So the place for euthanasia, I believe, is for the completely hopeless defective; nature's mistake; something we hustle out of sight, which should not have been seen at all." 

Foster Kennedy, while professor of neurology at Cornell University in New York, argued that all children with proven mental retardation ("feeblemindedness") over the age of five should be put to death.

These views earned him a mention in a much later article devoted mainly to such practices by the Nazis, and with the central topic of psychiatric genocide.

Neither Robert Foster Kennedy nor his first cousin, Sir Richard Dawson Bates would win too many plaudits for political correctness in our own day and age. Nonetheless, they certainly made an impact in their times.
