Carl Gustav Jung was a Swiss psychiatrist and psychoanalyst who founded analytical psychology. His work has been influential not only in psychiatry but also in anthropology, archaeology, literature, philosophy and religious studies. As a notable research scientist based at the famous Burghölzli hospital, under Eugen Bleuler, he came to the attention of the Viennese founder of psychoanalysis, Sigmund Freud. The two men conducted a lengthy correspondence and collaborated on an initially joint vision of human psychology. Freud saw in the younger man the potential heir he had been seeking to carry on his "new science" of psychoanalysis. Jung's researches and personal vision, however, made it impossible for him to bend to his older colleague's dogma and a breach became inevitable. This break was to have historic as well as painful personal repercussions that have lasted to this day. Jung was also an artist, craftsman and builder as well as a prolific writer. Many of his works were not published until after his death and some are still awaiting publication.
