The art world has recognized and celebrated Sol LeWitt (1928-2007) as an accomplished and influential conceptual artist since early in his career. As the son of Jewish emigrants from Russia, LeWitt spent his youth in Connecticut and later served in the Korean War. He started working at the Museum of Modern Art in 1960 and held his first retrospective there during 1978-1979. He was one of the first people to describe conceptual art when he wrote in Artforum in 1967, "In conceptual art the idea or concept is the most important aspect of the work . . . the idea becomes a machine that makes the art." His untitled woodcuts circa 1995 exude the same playfulness and perfunctory nature of his earlier works.
