Everyone knows that Eunice founded the Special Olympics to honor her sister Rosemary but do you know that her sister became "mentally disabled" because her father had her lobotomized?
Placid and easygoing as a child and teenager, the maturing Rosemary became increasingly assertive in her personality. She was reportedly subject to violent mood swings. Some observers have since attributed this behavior to her difficulties in keeping up with her active siblings, as well as the hormonal surges associated with puberty. In any case, the family had difficulty dealing with the often-stormy Rosemary, who had begun to sneak out at night from the convent where she was being educated and cared for.
In 1941, when Rosemary was 23, her father was told by her doctors that a cutting edge procedure would help calm her "mood swings that the family found difficult to handle at home". [2] Joseph Kennedy gave permission for the procedure to be performed by Dr. Walter Freeman, the director of the laboratories at St. Elizabeth's Hospital in Washington, D.C., together with his partner, James W. Watts, MD, from the University of Virginia. Watts performed his neurosurgical training at the Massachusetts General Hospital, and later he became the Chief of Neurosurgery at the George Washington University Hospital. Highly regarded, Dr. Watts later became the 91st president of the Medical Society of the District of Columbia. The procedure in question was a lobotomy.
At the time, only 65 lobotomies had been performed. Dr. Watts, who performed the surgery while Dr. Freeman supervised and observed, described the procedure:
We went through the top of the head, I think she was awake. She had a mild tranquilizer. I made a surgical incision in the brain through the skull. It was near the front. It was on both sides. We just made a small incision, no more than an inch." The instrument Dr. Watts used looked like a butter knife. He swung it up and down to cut brain tissue. "We put an instrument inside," he said. As Dr. Watts cut, Dr. Freeman put questions to Rosemary. For example, he asked her to recite the Lord's Prayer or sing "God Bless America" or count backwards. ... "We made an estimate on how far to cut based on how she responded." ... When she began to become incoherent, they stopped.
—James W. Watts [3]
Instead of producing the hoped-for result, however, the lobotomy reduced Rosemary to an infantile mentality that left her incontinent and staring blankly at walls for hours. Her verbal skills were reduced to unintelligible babble. Her mother, Mrs. Rose Kennedy, remarked that although the lobotomy stopped her daughter's violent behavior, it left her completely incapacitated. "Rose was devastated; she considered it the first of the Kennedy family tragedies."

On a happier note, after the lobotomy she was the only member of the family to register and vote republican!
