Carl Gustav Jung (1875-1961)

Born in 1875 in Basel, Switerzland, C. G. Jung was a medical doctor and psychiatrist who became a colleague, close confidant and heir apparent to Sigmund Freud.  Along with Freud, he opened up research into the unconscious and his work led to the popularization of interest in dreams and archetypes.  His correspondence with Bill W. contributed directly to the inclusion of the spiritual principle in A.A. and other 12-step programs.  He gave us the psychological type categories that led to the Myers-Briggs Type Indicator and coined the terms introvert and extravert.  He also coined the terms synchronicity (and his writing on that topic is the main reason for its continued popularity in our culture today) and collective unconscious – giving us a term for the deeper layer of the psyche that transcends the personal.
