Carl Gustav Jung (born Karl Gustav Jung, German; 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 and religious studies. Jung worked as a research scientist at the famous Burghölzli hospital, 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.
