Carl Jung - Astrologer?
Carl Jung was a famous psychoanalyst who studied with Freud but who eventually created an entirely new form of psychotherapy. The interesting thing about him (to me anyway) is that as he developed his theories of human behavior he became more and more involved in new age disciplines such as astrology. What he found was that one's astrological chart was rich in information that could help a psychoanalyst delve deep into ones psyche and find the deeply hidden issues and problems. Even today there are psychiatrists who quietly run and examine their patients' charts and use them as a guide in their therapy.
