Karen Horney (1885–1952), born Karen Danielsen near Hamburg, was a German psychiatrist and psychoanalyst. She trained in Berlin and worked in the United States from 1932. In papers written in the 1920s she contested Sigmund Freud's account of female development. She argued that penis envy is neither primary nor decisive for women, and that psychoanalytic views of femininity reflected a masculine standpoint. She also held that men's envy of motherhood ran as deep as the girl's envy of the penis.
In America she built a general theory of neurosis in which culture and disturbed human relationships took the place of instinct. Its main terms were the child's basic anxiety, the neurotic trends by which people seek safety from it, and the conflict between moving toward, against and away from people. Her last book added the idealized image, the search for glory and the tyranny of the should, forces that estrange a person from the real self.
Her critique of Freud's instinct theory in New Ways in Psychoanalysis1 cost her standing at the New York Psychoanalytic Institute, which disqualified her as a training analyst in 1941. She then founded the Association for the Advancement of Psychoanalysis and the American Institute for Psychoanalysis, and was the Institute's dean until her death. She is usually grouped with Erich Fromm, Harry Stack Sullivan and Clara Thompson in the so-called cultural school. Later readers have taken her as an early psychoanalytic critic of the theory of femininity and as a forerunner of humanistic psychology and of later theories of the self.
