Born on May 6, 1856 in Moravia, Sigmund Freud was an Austrian neurologist who, in the late 19th and early 20th centuries, developed the field of psychoanalysis. Freud developed many theories including those that focus on the unconscious, the interpretation of dreams, Id, ego, and super ego, and what is referred to as the psychosexual development theory.
