Alfred Adler (February 7, 1870, Rudolfsheim, Vienna – May 28, 1937) was an Austrian medical doctor, psychologist and founder of the school of individual psychology. In collaboration with Sigmund Freud and a small group of Freud's colleagues, Adler was among the co-founders of the psychoanalytic movement as a core member of the Vienna Psychoanalytic Society. He was the first major figure to break away from psychoanalysis to form an independent school of psychotherapy and personality theory.
