André Robert Breton (French: [ɑ̃dʁe ʁɔbɛʁ bʁətɔ̃]; 19 February 1896 – 28 September 1966) was a French writer and poet. He is known best as the co-founder, leader, and principal theorist of surrealism. His writings include the first Surrealist Manifesto (Manifeste du surréalisme) of 1924, in which he defined surrealism as "pure psychic automatism".
Along with his role as leader of the surrealist movement he is the author of celebrated books such as Nadja and L'Amour fou. Those activities, combined with his critical and theoretical work on writing and the plastic arts, made André Breton a major figure in twentieth-century French art and literature.
André Breton was the only son born to a family of modest means in Tinchebray (Orne) in Normandy, France. His father, Louis-Justin Breton, was a policeman and atheistic, and his mother, Marguerite-Marie-Eugénie Le Gouguès, was a former seamstress. Breton attended medical school, where he developed a particular interest in mental illness. His education was interrupted when he was conscripted for World War I.
