( 1856–1939), Austrian neurologist and psychotherapist. He was the first to emphasize the significance of unconscious processes in normal and neurotic behavior and was the founder of psychoanalysis as both a theory of personality and a therapeutic practice. He proposed the existence of an unconscious element in the mind that influences consciousness and of conflicts in it between various sets of forces. His theory of the sexual origin of neuroses aroused great controversy.
