C.G.Jung 
Lord of the Underworld

Carl Gustav Jung is one of the seminal figures in the history of depth psychology. An enormously influential and original thinker, Jung was for some time Freud’s principal disciple, but he became more and more critical of the Freudian emphasis on repressed sexual tendencies and after the publication of "Symbols of Transformation" in 1912, Jung broke away from Freud to develop his own technique of 'analytical psychology’.
