Jean Dubuffet (1901 - 1985) was a French painter, sculptor, lithographer and writer, close to the Surrealists and the spirit of the Naive Artists. He was the first theoretician of an art style which he gave the name of "art brut" to describe the kind of work that he collected and aspired toward: the untrained, outsider art of alienated groups, including children and the mentally ill.
His own art prints are purposefully “deskilled,” often possessing the spontaneity and crude aesthetic of finger paintings. He was an experimental artist in the way he found new ways of applying materials to his artwork. For example, he used sand or plaster in his paintings and incorporated items discarded on the street into his sculptures.
