Sol LeWitt (1928-2007) was an American painter, sculptor and graphic artist. He went down in art history as a pioneer of conceptual art and minimalism.
Sol LeWitt's conception of art was marked by the transition from modernism to postmodernism; it stipulated that the concept of a work should be in the foreground. From this LeWitt developed the term Conceptual Art.
In his works, Sol LeWitt experiments with architectural spatial structures, grid patterns and grid constructions that are reduced to a minimum. These works are not about a narrative or, say, a message, but about the work-concept itself, the structure of the image, the coherence of the forms and colors, etc.
"I wasn't really interested in objects. I was interested in the idea." - Sol LeWitt
