Jacques Lacan

Jacques Marie Émile Lacan (, ; ; 13 April 1901 – 9 September 1981) was a French psychoanalyst and psychiatrist. Described as "the most controversial psycho-analyst since Freud", Lacan gave annual seminars in Paris from 1952 to 1980 and published papers that were later collected in the book ''Écrits''. Transcriptions of the seminars 1953–1980 were published. His work made a significant impact on continental philosophy and cultural theory in areas such as post-structuralism, critical theory, feminist theory and film theory, as well as on the practice of psychoanalysis itself.

Lacan discussed the whole range of Freudian concepts, emphasizing the philosophical dimension of Freud's thought and applying concepts derived from structuralism in linguistics and anthropology to his own work, which he augmented with predicate logic and topology. Taking this new direction, and introducing controversial innovations in clinical practice, led to expulsion for Lacan and his followers from the International Psychoanalytic Association. In consequence, Lacan went on to establish new psychoanalytic institutions to promote and develop his work, which he declared to be a "return to Freud", in opposition to prevalent trends in psychology and institutional psychoanalysis which adapted Freud’s ideas to social norms.
