Al Held (October 12, 1928 – July 27, 2005) was an American Abstract expressionist painter. He was particularly well known for his large scale Hard-edge paintings. As an artist, multiple stylistic changes occurred throughout his career, however, none of these occurred at the same time as any popular emerging style or acted against a particular art form. In the 1950s his style reflected the abstract expressionist tone and then transitioned to a geometric style in the 60s. During the 1980s there was a shift into acrylic painting that emphasized bright geometric space that’s deepness reflected infinity. From 1962 to 1980 he was a professor of art at Yale University.
