Jean Philippe Arthur Dubuffet was a French painter and sculptor known for founding the Art Brut movement. Embracing "raw art", Dubuffet took inspiration from the art of children, prisoners, and other groups of people commonly viewed as unsophisticated or uncultured. Believing that there was merit in re-examining the traditional standards of beauty, Dubuffet became a prolific artist that enjoyed the friendship of Henri Matisse, another seminal figure of modern art, and audiences that stretched between New York and Paris. His use of uncommon materials, such as rock, oil, and leaves, along with his unconventional renderings of his subjects would cement his role as one of the leading modern artists of the 20th century. The artist would go on to form the Compagnie de l’Art Brut with André Breton and Slavko Kopac; the Art Brut movement would also be influential in the creation of the Collection de l'art brut. Today, his works are held in the collections of the Art Institute of Chicago, The Museum of Modern Art in New York, the National Gallery of Art in Washington, D.C., and the Centre Georges Pompidou in Paris.
