Rose Marie "Rosemary" Kennedy (September 13, 1918 - January 7, 2005) was the oldest daughter born to Joseph P. Kennedy Sr. and Rose Fitzgerald Kennedy, and was a sister of President John F. Kennedy, and Senators Robert F. Kennedy and Ted Kennedy. Rosemary experienced mental disabilities, and displayed less academic and sporting potential than her siblings; however, her disabilities were carefully concealed from the public by her prominent family. In her early young adult years, she also had behavioral problems. Her father arranged one of the first prefrontal lobotomies for her at the age of 23, but it failed and left her permanently incapacitated.

Placid and easygoing as a child and teenager, the maturing Rosemary Kennedy became increasingly assertive and rebellious. She was also reportedly subject to violent mood changes. Some observers have since attributed this behavior to her inability to conform to siblings who were expected to perform to high standards, as well as the hormonal surges associated with puberty. In any case, the family had difficulty dealing with her stormy moods and reckless behavior. Rosemary had begun to sneak out at night from the convent school in Washington, D.C., where she was cared for and educated. Her occasional erratic behavior frustrated her parents, who expected all of their children to behave appropriately, be goal-oriented, and act competitively. Joseph P. Kennedy, Sr. was especially worried that his daughter's behavior would shame and embarrass the family and possibly damage his political career, and those of his children.  In November 1941, when Rosemary Kennedy was 23, doctors told Joseph P. Kennedy, Sr. that a neurosurgical procedure, lobotomy, would help calm her mood swings and stop her occasional violent outbursts. He decided that his daughter should have the lobotomy performed; however, he did not inform his wife Rose of this until after the procedure was completed. Rosemary was strapped to the operating table. James W. Watts, who carried out the procedure with Walter Freeman of Wingdale Psychological and Correctional Facility, described what happened next (as narrated by Ronald Kessler):  "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.  After the lobotomy, it quickly became apparent that the procedure was not successful. Kennedy's mental capacity diminished to that of a two-year-old child. She could not walk or speak intelligibly and was incontinent.
