Jacques Marie Émile Lacan ( 13 April 1901 – 9 September 1981)

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
Lacan was born in Paris, the eldest of Emilie and Alfred Lacan's three children. His father was a successful soap and oils salesman. His mother was ardently Catholic—his younger brother went to a monastery in 1929 and Lacan attended the Jesuit Collège Stanislas during the period 1907–1918. During the early 1920s, Lacan attended right-wing Action Françaisepolitical meetings, of which he would later be highly critical, and met the founder, Charles Maurras. By the mid-1920s, Lacan had become dissatisfied with religion and became an atheist. He quarreled with his family over this issue.
