Jacques Marie Émile Lacan 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.

From 1952 to 1980 French psychoanalyst and psychiatrist Jacques Lacan gave an annual seminar in Paris. The Books of the Seminar are edited by Jacques-Alain Miller.
