Rosemary Kennedy
September 13, 1918) is the oldest daughter of Rose and Joseph P. Kennedy, Sr. and the younger sister of U.S. President John F. Kennedy.
Rosemary was a shy and mentally slow child, symptoms which some believe point to dyslexia. The family had difficulty dealing with Rosemary's problems, and in 1941 her father asked a neurosurgeon to perform a prefrontal lobotomy — this was considered a magical cure. This did not have the effect that was foreseen, and afterwards Rosemary was incapable of living a normal life. She has been living in an institution in Wisconsin since that time.
