Carl Gustav Jung (/jʊŋ/ YUUNG; German: [kaʁl ˈjʊŋ]; 26 July 1875 – 6 June 1961) was a Swiss psychiatrist and psychoanalyst who founded analytical psychology. Jung's work has been influential in the fields of psychiatry, anthropology, archaeology, literature, philosophy, psychology, and religious studies. Jung worked as a research scientist at the Burghölzli psychiatric hospital, in Zurich, under Eugen Bleuler. During this time, he came to the attention of Sigmund Freud, the founder of psychoanalysis. The two men conducted a lengthy correspondence and collaborated, for a while, on a joint vision of human psychology.
