Anna Freud

Austrian psychoanalyst. She was one of the first and leading proponents of child psychoanalysis and “Ego Psychology.” Trained by her father, Sigmund Freud, she began her career and, while working on child analysis, developed psychoanalytic theory in close collaboration with him. He is considered the founder of the “Instinct Theory” and “Classical Analysis,” which link psychoanalysis to medicine and biology, in contrast to Melanie Klein, an advocate of the “Object Relations Theory” in psychoanalysis.
