Sol LeWitt (1928-2007) was an American artist best known for his pioneering role in the development of conceptual art and minimalism. Born in Hartford, Connecticut, LeWitt was a self-taught artist who initially worked as a graphic designer. In the 1960s he became associated with the minimalist and conceptual art movements, which emphasised the idea behind a work of art rather than its physical execution.

LeWitt is best known for his wall drawings, which he began making in the 1960s. These drawings consisted of simple geometric shapes and lines that followed a set of written instructions. The drawings were executed by trained assistants who followed LeWitt's instructions to the letter, resulting in a standardised and repetitive visual language. This approach challenged the traditional notion of the artist as a solitary creator and emphasised the idea that art was a product of systems and processes rather than individual genius.

In addition to his wall drawings, LeWitt created sculptures, prints and photographs, all characterised by their simplicity and repetitive form. He was also a major influence on the development of the 'systems art' movement, which sought to create art through mathematical and logical processes.

LeWitt's work has been widely exhibited in museums and galleries around the world and is included in many major public collections. He received numerous awards and honours during his lifetime, including the National Endowment for the Arts Visual Arts Fellowship in 1972 and the Skowhegan Medal for Painting and Sculpture in 1993.

Sol LeWitt's impact on the art world cannot be overstated. He is widely recognised as one of the most important artists of the 20th century, and his legacy continues to influence contemporary artists today. His commitment to conceptual and minimal art, and his innovative approach to making art, continue to inspire and challenge artists, critics and audiences alike.
