After World War I, French poet and literary theorist André Breton began to link at first with Dadaism but broke with that movement to write the first manifesto of surrealism in 1924.
People best know this theorist as the principal founder. His writings include the
Surrealist Manifesto
(Manifeste du surréalisme), in which he defined this "pure psychic automatism."
