For almost half a century (1891-1938), Sigmund Freud lived and worked in a classic tenement house in Vienna’s Hochgrunderzeit. During these years, Freud’s family moved many times to different floors of the tenement house. The greatest works were created here (“The Interpretation of Dreams,” “On Psychoanalysis,” “Ego and Id” and others). The famous Psychological Society of Wednesdays-the first psychoanalytic study group was held here. After the annexation of Austria by Nazi Germany, Freud had to escape from Vienna to London, where he died at the age of 83 (suffering from cancer)-he ended his life with an overdose of morphine with the help of a doctor friend.
