Richard Anuszkiewicz (American, 1930 - 2020) is a contemporary American artist best known for his mesmerizing Op Art paintings. Anuszkiewicz's works are saturated with vibrant color arranged in jarring geometric abstract compositions, formally exploring the phenomena of light, color, and line and their effects on human perception. Anuszkiewicz’s interest in optics perhaps stems from his study under famed colorist Josef Albers while attaining his MFA at Yale University between 1953 and 1955. Later in his artistic career, he experimented further with the physical effects of optic phenomena through sculpture, creating geometric works that mimic his two-dimensional compositions. Born on May 23, 1930 in Erie, PA, his work was well-received in the 1960s and beyond, garnering his inclusion in the Venice Biennale and documenta, as well as various honors including a 2000 Lee Krasner Award. The artist passed away in 2020 in Englewood, NJ.

Anuszkiewicz is best known for his use of a technique he called "color performance." He described color as the most important actor in his work: "the image in my work has always been determined by what I wanted the color to do. Color function becomes my subject matter, and its performance is my painting."
