Sigmond Freud
Freud had many people who studied his work that in turn became famous psychoanalytic theorists in their own right. ... Erikson was trained and analyzed by Freud’s daughter, Anna, at the Vienna Psychoanalytic Institute (Encyclopedia of Psychology). Erikson thought that Freud’s theory was too short and had few stages, so he decided to add eight stages covering the entire life span, from birth to death. ... Erikson first five stages are closely related to Freud’s stages. Erikson (like Freud) believed that problems of adult life echo unresolved conflicts of childhood (The Developing Person Through the Life Span). ... The first of Erikson’s virtues is hope, and like Freud’s begins with the Oral Sensory stage.
