The name Sigmund Freud is inseparably associated with the city of Vienna and Berggasse 19. It was here that the founder of psychoanalysis lived and worked from 1891 to 1938. His former surgery at Berggasse 19 was opened to the public for the first time in June 1971, thanks to the efforts of his daughter Anna Freud. Today, the Sigmund Freud Museum is testimony to the life and work of Austria's most famous 20th century scientist. It was here that Freud produced his interpretation of dreams, his case studies and his works on cultural theory. It was here too that his patients came for their psychoanalysis sessions. Freud's surgery also contained his famous couch, the subject matter of an exhibition of its own, "The Couch. About thinking and lying" on the occasion of the 150th anniversary of Sigmund Freud's birth in 2006.
