André Robert Breton was a French writer and poet, known as a principal theorist and co-founder 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 20th-century French art and literature.
