The Vienna Psychoanalytic Society (German: Wiener Psychoanalytische Vereinigung, WPV), formerly known as the Wednesday Psychological Society, was the oldest psychoanalysis society in the world. In 1908, reflecting its growing institutional status as the international psychoanalytic authority of the time, the Wednesday group was reconstituted under its new name with Sigmund Freud as President, a position he relinquished in 1910 in favor of Alfred Adler.[1] During its 36-year history, between 1902 and 1938, the Society had a total of 150 members.
