Carl Alanson Whitaker (1912–1995) was an American physician and psychotherapy pioneer family therapist.
"Carl Whitaker was one of the founding generation of family therapists who broke the rules of the psychotherapeutic orthodoxies of the time, such as that therapy focused on a single client and was totally divorced from family life," said Richard Simon, editor of The Family Therapy Networker, a leading publication in the field. "His idea was that the entire family was the client." Dr. Whitaker, known for his charm and charismatic manner, was one of the most powerful voices in shaping the practice of family therapy as it began to develop in the 1960s. Often provocative in his teaching, he told one interviewer, "Every marriage is a battle between two families struggling to reproduce themselves."[1]
