Anna Freud was the youngest of Sigmund Freud's six children. While she began her career influenced by the theories of her father, she was far from living in his father's shadow. She made important contributions of her own to psychology, including founding child psychoanalysis and summarizing the ego's defense mechanisms in her book The Ego and the Mechanisms of Defense (1936).
Read more about her life, career, and influence on psychology and psychoanalysis in the following Anna Freud biography.
