Jean Dubuffet rejected artistic traditions. He strove to create a unique visual language with which to portray the everyday world. One of the most important early theorists and collectors of "art brut," Dubuffet was a major force in the recognition and appreciation of outsider art. Naive and unconventional visions of reality influenced the development of his own singularly personal style and imagery. He explored and experimented with many printmaking techniques throughout his career, most notably silkscreen and lithography.Dubuffet has been the subject of numerous museum and gallery exhibitions, and his work is included in important public and private collections worldwide. His personal collection of outsider art was the foundation of the Collection de l'Art Brut in Lausanne, Switzerland.
