Jacques Marie Émile Lacan (; ; 13 April 1901 – 9 September 1981), known simply as Jacques Lacan, was a French psychoanalyst and psychiatrist who has been called "the most controversial psycho-analyst since Freud". Giving yearly seminars in Paris from 1953 to 1981, Lacan influenced many leading French intellectuals in the 1960s and the 1970s, especially those associated with post-structuralism. His ideas had a significant impact on post-structuralism, critical theory, linguistics, 20th-century French philosophy, film theory and clinical psychoanalysis.
