American, minimalist painter Sol Lewitt (1928-2007) used the grid as a foundation for his many artworks. Seeing himself in the role of architect or composer, Lewitt was most concerned with the concept behind the piece rather than the final product. His geometrical compositions stripped away extraneous information and presented the bare essentials. His prolific two and three-dimensional work ranged from Wall Drawings, over 1100 of which have been executed, to photographs and hundreds of works on paper and extends to structures in the form of towers, pyramids, geometric forms, and progressions. LeWitt helped revolutionize the definition of art in the 1960s with his famous notion that “the idea becomes a machine that makes the art.”
