Rose Marie "Rosemary" Kennedy (September 13, 1918 – January 7, 2005) was the oldest daughter born to Joseph P.
Kennedy Sr.
and Rose Fitzgerald Kennedy.
She was a sister of President of the United States John F.
Kennedy and Senators Robert F.
Kennedy and Ted Kennedy.
Kennedy was intellectually disabled and was educated separately from other students; however, she was able to travel and to participate in social functions with her family.
Kennedy was presented to King George VI and Queen Elizabeth at Buckingham Palace in 1938.
In her early young adult years, Kennedy experienced seizures and violent mood swings.
In response to these and other difficulties, Kennedy's father arranged a prefrontal lobotomy for Kennedy in 1941 when she was 23 years of age.
The procedure failed, leaving Kennedy permanently incapacitated and rendering her unable to speak intelligibly.
Kennedy spent most of the rest of her life being cared for at St.
Coletta, an institution in Jefferson, Wisconsin.
The truth about her situation and whereabouts was kept secret for decades.
While she was initially isolated from her relatives following her lobotomy, Kennedy visited with her family during her later life.
