Karl Benjamin (December 29, 1925 – July 26, 2012) was an American painter of vibrant geometric abstractions, who rose to fame in 1959 as one of four Los Angeles-based Abstract Classicists and subsequently produced a critically acclaimed body of work that explores a vast array of color relationships. Working quietly at his home in Claremont, CA, he developed a rich vocabulary of colors and hard-edge shapes in masterful compositions of tightly balanced repose or high-spirited energy.
