Information: - Sigmund Freud ( born Sigismund Schlomo Freud; 6 May 1856 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst. Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austro-Hungarian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. In 1938 Freud left Austria to escape the Nazis. He died in exile in the United Kingdom in 1939. - Carl Gustav Jung (26 July 1875 6 June 1961) was a Swiss psychiatrist and psychoanalyst who founded analytical psychology. His work has been influential not only in psychiatry but also in anthropology, archaeology, literature, philosophy and religious studies. As a notable research scientist based at the famous Burgholzli hospital, under Eugen Bleuler, he came to the attention of the Viennese founder of psychoanalysis, Sigmund Freud. The two men conducted a lengthy correspondence and collaborated on an initially joint vision of human psychology. Freud saw in the younger man the potential heir he had been seeking to carry on his "new science" of psychoanalysis. Jung's researches and personal vision, however, made it impossible for him to bend to his older colleague's dogma and a breach became inevitable. This break was to have historic as well as painful personal repercussions that have lasted to this day. Only latterly has it become clear, how much Jung owed to his fortuitous marriage to the heiress, Emma Rauschenbach, who was not only devoted to him, but forgiving and, in all likelihood, his intellectual equal. Jung was also an artist, craftsman and builder as well as a prolific writer. Many of his works were not published until after his death and some are still awaiting publication. - Burgholzli is the common name given for the psychiatric hospital of the University of Zurich, Switzerland.
