Anna Freud was born in Vienna
in 1895, the youngest of Sigmund Freud
and Martha Freud's six children. She was the only member of the family to follow in her father's footsteps and the whole of her working life was devoted to psychoanalysis
. As a young woman she became his secretary
, companion and pupil and in 1922 she began to practice as a psychoanalyst
and became an active member of the International Psychoanalytical Association
. By 1925 she had become Secretary of the Vienna Psychoanalytic
Training Institute and in the late 1920s her working life was divided between working with children and supervising the training of would-be analysts. She taught the child analysis seminar and an applied analysis course in Psychoanalytic Pedagogy which was also attended by Viennese schoolteacher
s and social worker
By the mid 1930s Anna combined the roles of secretary, nurse and aide to her father who was by then in his early 80s and in failing health. She was also regarded by many as the obvious successor as the leader of the psychoanalytic movement on the strength of her writing and her clinical practice. She remained broadly faithful to her father's ideas, however she became more interested in the dynamics of the psyche than in its structure. Specifically, she developed Sigmund Freud's notion of the ego, in particular the part it plays in the defence mechanisms. A significant point in her thinking on this subject was the publication of The Ego and the Mechanisms of Defence in 1937. The 'ego psychology' movement which grew out of this work was significant in that it encouraged the applications of Freudian theory beyond psychopathology and into the territories of developmental and social psychology.
Anna Freud died in 1982.
