The Swiss psychologist and psychiatrist Carl Gustav Jung (1875-1961) was a founder of modern depth psychology.

Carl Jung was born on July 26, 1875, in Kesswil, the son of a Protestant clergyman. When he was four, the family moved to Basel. As he grew older, his keen interest in biology, zoology, paleontology, philosophy, and the history of religion made the choice of a career quite difficult. However, he finally decided on medicine, which he studied at the University of Basel (1895-1900). He received his medical degree from the University of Zurich in 1902. Later he studied psychology in Paris.

In 1903 Jung married Emma Rauschenbach, his loyal companion and scientific collaborator until her death in 1955. The couple had five children. They lived in Küsnacht on the Lake of Zurich, where Jung died on June 6, 1961.

Jung began his professional career in 1900 as an assistant to Eugen Bleuler at the psychiatric clinic...
