"By the 1960s his work evolved into something leaner and flatter... which nodded both toward Rothko and Hofmann and linked Opper to Color Field art... His feel for color and sense of rhythm are particularly acute. He exemplifies a certain quality of grace in orthodox Abstract Expressionism." - Michael Kimmelman, The New York Times, 2003
John Opper, an influential painter associated with the New York School, created art for over six decades. His artistic journey evolved from abstract gestural works to pure abstraction, emphasizing the profound connection between art and viewers. Opper co-founded the American Abstract Artists in 1936. His artwork can be found in prestigious museum collections, including the Museum of Modern Art, the Whitney Museum of American Art, and the Metropolitan Museum of Art in New York City.
