Jung was born on July 26, 1875 in Kesswil, Switzerland, a town of mostly fisherman and farmers. Jung was the only surviving child of Paul Jung, a Protestant minister, and Emilie Preiswerk. The Preiswerks were Swiss citizens related to the vom Tieg, an ancient royal family from Basel, while the Jung’s were Germans exiles whose ancestry included a later conversion from Roman Catholic to Protestant in the 1700's. At the tender age of four years old the Jung family moved to Basel; soon after, Paul began teaching his son Latin. Carl’s gift for language would prove lasting; he would eventually master a variety, including English, French, ancient Greek, and Sanksrit.
Jung was an introverted child possessed of great intelligence. In other words, Carl was a walking bull’s-eye for any playground bully. Indeed, while attending a boarding school in Basel, his classmates tormented the timid Jung who typically played alone. In Deirdre Bair's book "Jung: A Biography," she writes the “... parents of the village children deliberately kept them away from the odd little boy, whose parents were so peculiar” (p. 22). After matriculating from the Humanistisches Gymnasium, the bullying Jung endured culminated in a traumatic incident when, at age 12, a classmate shoved him so hard he was knocked unconscious. Carl began to faint frequently for years afterward and later described the experience as a childhood neurosis.
Jung’s grandfather had been a professor of surgery at the University of Basel. Despite C. G. Jung’s first inclination toward a career in archeology, the very realistic young man realized that such a profession would never provide him the job and financial security he needed. Jung eventually picked medicine at the University of Basel which included both an M.D. degree and a doctorate allowing him to be accepted as an academic with the title of Privat-docent in Psychiatry at the University of Zurich (Dissertation, “On the Psychology and Pathology of So-Called Occult Phenomena”. Jung’s most significant mentorship came after he graduated, taking he took a staff position at the Burghölzli Mental Hospital in Zurich under the tutelage of Eugen Bleuler. There he also achieved world acclaim as research scientist in Psychiatry performing pioneering studies on the Word Association Test.
