Remembering History: "Rosie" "Rosemary" Rose Marie Kennedy (1918–2005). Known as "Rosemary" or "Rosie", she was rendered incapable of intelligible speech or caring for herself by a prefrontal lobotomy at age 23 – a new neurosurgical technique of the time and requested by her father – that was intended to cure her increasing mood swings and make her more manageable. The operation instead reduced her to an infantile state. From 1949, she lived in a residential care facility in Jefferson, Wisconsin until her death.
