Sol LeWitt (Hartford, Connecticut, 1928 – New York, New York, 2007) was an American artist recognized as a founder of both Minimal and Conceptual art. His central proposition, that an artwork's instructions matter more than its physical execution, separated authorship from the artist's own hand and reshaped the possibilities of postwar sculpture and drawing.

LeWitt completed his BFA at Syracuse University before serving in the Korean War and settling in New York, where in the early 1960s he worked the night shift as a Museum of Modern Art receptionist, alongside fellow artists Dan Flavin, Robert Mangold, and Robert Ryman, and the future critic Lucy Lippard. Watching Abstract Expressionism give way to Pop art, LeWitt found himself drawn to neither, gravitating instead toward serial, near-mathematical systems: modular cubes and grid structures whose variations were generated by a fixed set of rules rather than intuition.
