From Wikipedia, the free encyclopedia.
Rosemary Kennedy (born September 13, 1918) is the oldest daughter of Rose and Joseph P. Kennedy, Sr
Rosemary was born slightly retarded. The family had problems dealing with this, 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.
