In 1906, Sigmund Freud began a correspondence with Carl Gustav Jung who was by then already an academically acclaimed researcher into word-association and the Galvanic Skin Response, and a lecturer at Zurich University, although still only an assistant to Eugen Bleuler at the Burghölzli Mental Hospital in Zürich. In March 1907, Jung and Ludwig Binswanger, also a Swiss psychiatrist, travelled to Vienna to visit Freud and attend the discussion group. Thereafter, they established a small psychoanalytic group in Zürich University.
