"Sol LeWitt (1928 — 2007) was an American artist famous for his wall drawings and sculptures, who played a leading role in the Conceptual art movement.
His belief in the artist as a generator of ideas was instrumental in the transition from the modern to the postmodern era. Conceptual art, expounded by LeWitt as an intellectual, pragmatic act, added a new dimension to the artist's role that was distinctly separate from the romantic nature of Abstract Expressionism. LeWitt believed the idea itself could be the work of art, and maintained that, like an architect who creates a blueprint for a building and then turns the project over to a construction crew, an artist should be able to conceive of a work and then either delegate its actual production to others or perhaps even never make it at all.
LeWitt's work ranged from sculpture, painting, and drawing to almost exclusively conceptual pieces that existed only as ideas or elements of the artistic process itself.
