Swiss psychiatrist Carl Gustav Jung was born July 26, 1875, in Kesswil, Switzerland. The only son of a Protestant clergyman, Jung was a quiet, observant child who packed a certain loneliness in his single-child status. However, perhaps as a result of that isolation, he spent hours observing the roles of the adults around him, something that no doubt shaped his later career and work.
Jung attended the University of Basel. There, he was exposed to numerous fields of study, including biology, paleontology, religion and archaeology, before finally settling on medicine. Jung graduated the University of Basel in 1900 and obtained his M.D. two years later from the University of Zurich.
Carl Jung established analytical psychology. He advanced the idea of introvert and extrovert personalities and the power of the unconscious.
The final break came in 1912 when Jung published Psychology of the Unconscious. In it, Jung examined the unconscious mind and tried to understand the symbolic meaning of its contents. In the process, the work also took head-on a number of Freud’s theories.
