Al Held (1928-2005) was a leading American abstract painter whose work transformed geometric abstraction in the postwar era. Born in Brooklyn, New York, he studied at the Art Students League and later in Paris, where he developed a lifelong commitment to abstraction. Held first gained recognition in the 1950s with expressive Abstract Expressionist paintings before shifting toward bold geometric forms and large-scale compositions. By the 1960s and 1970s, he became known for monumental canvases that explored space, perspective, and visual perception through vibrant color and complex structures. A longtime professor at Yale University, Held influenced generations of artists. His work is held in major museum collections worldwide and remains a landmark in modern American art.
