Carl Gustav Jung (26 July 1875 – 6 June 1961), often referred to as C. G. Jung, was a Swiss psychiatrist and psychotherapist who founded analytical psychology. His work has been influential not only in psychiatry but also in philosophy, anthropology, archaeology, literature, and religious studies. He was a prolific writer, though many of his works were not published until after his death.
Jung created some of the best known psychological concepts, including the archetype, the collective unconscious, the complex, and extraversion and introversion.
