American artist whose work provides a link between minimalism and conceptual art.

LeWitt was the son of Russian immigrants. He attended Syracuse University (B.F.A., 1949) and, following military service in Japan and Korea, moved in 1953 to New York City. There he worked as a graphic designer for the architect I.M. Pei (Pei, I.M.) in 1955 and 1956. Following a brief period of trying out the Abstract Expressionist style in the 1950s, LeWitt in the early 1960s began to pursue an essentialist approach to art that was less emotional yet still rich in speculation and interest. He started to work serially, concentrating on sculptures of various gridlike axial arrangements of modular white aluminum, wood, or metal cubes.

His work in this vein led him to conclude that the planning of a work of art would always be more significant than its execution as an object. In a statement that became a credo of conceptual art, LeWitt wrote in Artforum magazine in 1967:

Begun in 1968 and running to more than 1,000 examples, his extensive series of numbered wall drawings applied these principles. LeWitt provided written instructions and sometimes a small sketch for each of these abstract works, and the drawing (usually a monumental work painted directly on a gallery wall, as in Wall Drawing \\# 652 【1990】) was executed by his assistants and others. LeWitt's sculptures, prints, and drawings examined endlessly thoughtful and surprising possibilities of visual extrapolation within a concentration on pattern, geometry, and repetition.
