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 yearly seminars in Paris, from 1953 to 1981, and published papers that were later collected in the book ''Écrits''. Transcriptions of his seminars, given between 1954 and 1976, were also 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 took up and 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 its development in his own work, which he would further augment by employing formulae from 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 collusive of adaptation to social norms.
