Jean Dubuffet (1901–1985) was a renowned French painter and sculptor who played a pivotal role in the post-war avant-garde movement. He's best known for his philosophy of "Art Brut" (Raw Art), which championed art created outside the traditional confines of the art world, particularly by non-professionals and those in psychiatric institutions. Dubuffet's own works often exuded a raw, primitive style, using unconventional materials like sand, gravel, and tar. He drew inspiration from graffiti, children's drawings, and the art of the mentally ill. His pieces have been exhibited in prestigious institutions across the globe, including the Museum of Modern Art in New York and the Tate Modern in London. Through his unique approach, Dubuffet challenged academic artistic standards and celebrated the power of uninhibited creative expression.
