Ellsworth Kelly (1923-2015) was an American painter, sculptor, and printmaker. Kelly became a major abstract artist in the US after World War II. As early as the 1950s, he developed an individual approach that influenced the course of Minimal art, Color Field painting, and hard-edge paintingwithout becoming fully a part of any of these movements. Although Kelly can now be considered an essential innovator and contributor to the American art movement, he was not always seen as such. However, by the late 1950s, Kelly had an international reputation.
