Jean Philippe Arthur Dubuffet (31 July 1901 – 12 May 1985) was a French painter and sculptor of the Ecole de Paris (School of Paris). His idealistic approach to aesthetics embraced so-called "low art" and eschewed traditional standards of beauty in favor of what he believed to be a more authentic and humanistic approach to image-making. He is perhaps best known for founding the art movement art brut, and for the collection of works—Collection de l'art brut—that this movement spawned. Dubuffet enjoyed a prolific art career, both in France and in America, and was featured in many exhibitions throughout his lifetime.
