She was the eldest daughter born to Joseph P. Kennedy Sr. and Rose Fitzgerald Kennedy. She was a sister of President John F. Kennedy and Senators Robert F. and Ted Kennedy. Rosemary Kennedy was born at her parents' home in Brookline, Massachusetts on September 13, 1918 During her birth, the doctor was not immediately available because of an outbreak of the Spanish influenza epidemic and the nurse ordered Rose Kennedy to keep her legs closed, forcing the baby's head to stay in the birth canal for two hours. The action resulted in a harmful loss of oxygen. At age 16, Kennedy was sent to the Sacred Heart Convent in Elmhurst, Providence, Rhode Island, where she was educated separately from the other students In 1938, Kennedy was presented as a debutante to King George VI and Queen Elizabeth at Buckingham Palace during her father's service as the United States Ambassador to the United Kingdom. According to Kennedy's sister Eunice, when Rosemary returned to the United States from the United Kingdom in 1940, she became "increasingly irritable and difficult" at the age of 22. Kennedy would often experience convulsions and fly into violent rages, during which she would hit and injure others. After being expelled from a summer camp in western Massachusetts and staying only a few months at a Philadelphia boarding school, Kennedy was sent to a convent school in Washington, D.C. Her occasionally erratic behavior frustrated her parents; her father was especially worried that Kennedy's behavior would shame and embarrass the family and damage his and his children's political careers. When Kennedy was 23 years old, doctors told her father that a lobotomy would help calm her mood swings and stop her occasional violent outbursts Joe Sr. decided that Rosemary should have a lobotomy; however, he did not inform his wife of this decision until after the procedure was completed.The procedure took place in November 1941. It was quickly apparent that the procedure had caused immense harm. Kennedy's mental capacity diminished to that of a two-year-old child. She could not walk or speak intelligibly and was incontinent After the lobotomy, Kennedy was immediately institutionalized. She initially lived for several years at Craig House, a private psychiatric hospital 90 minutes north of New York City In response to her condition, Kennedy's parents separated her from her family. Rose Kennedy did not visit her for 20 years. Joe Sr. did not visit his daughter at the institution at all. In 1961, after Joe Sr. had a stroke that left him unable to speak and walk, Rosemary's siblings were made aware of her location. Rosemary's condition was revealed publicly by her sister Eunice in a 1962 interview to The Saturday Evening Post, but her lobotomy did not become public knowledge until 1987, Following her father's death in 1969, the Kennedys gradually involved Rosemary in family life again.She was occasionally taken to visit relatives By that time, Rosemary had learned to walk again, but did so with a limp. She never regained the ability to speak clearly and her arm was palsied Kennedy died from natural causes on January 7, 2005, aged 86,at the Fort Atkinson Memorial Hospital in Fort Atkinson, Wisconsin, She was buried beside her parents at Holyhood Cemetery in Brookline, Massachusetts. #rosemarykennedy #thekennedys - @celebrity.death.s
