Yeah, Rosemary was an embarrassment to the Family, so her old man had her temporal lobes scrambled, then put her away. It was a disgraceful thing.
I always knew the Kennedys had a sister who spent her life institutionalized but I never knew the ghastly story until today when this thread piqued my curiosity about Kennedy family history and I started down the rabbit hole of Wiki links.
Reading the account of Rosemary's "surgery" is just horrifying.
