Sol LeWitt was born in Hartford, Connecticut, in 1928. He graduated with a degree in fine arts from Syracuse University, New York, in 1949. He then worked for an architectural firm as a graphic designer. In 1960 he worked at the Museum of Modern Art in New York, where the artists Robert Mangold and Dan Flavin were among his co-workers. They were all in search of a new direction in art. After previously concentrating on paintings and reliefs, LeWitt began making three-dimensional works. He created precisely measured cubes put together according to a mathematical formula. Sol LeWitt is among the most important artists of Minimal Art and Conceptual Art. He had his first solo show in 1965 in London. He taught at both New York University and the School of Visual Arts. In 1968 he began making wall drawings; these works, stringent at first, would later become more colourful. By the time he died he had created 1,200 wall drawings. LeWitt’s works were seen at documenta 4 in 1968 and are represented in numerous distinguished museum collections. He died in New York in 2007.
