Dr. Sigmund Freud, 1856-1939, The Father of Psychotherapy. He developed the theory of psychoanalysis, a clinical method for treating mental disturbances and illness through dialogue between patient and psychoanalyst. This method remains an important influence across all the humanities. The concept of the unconscious was central to Freud's account of the mind, along with the study and analysis of dreams. He proposed that the human psyche could be divided into three parts: Id, ego and super-ego. His concepts and explanations were pivotal to the expansion of the study of psychological troubles.
