Al Held (1928 - 2005) was an American Abstract expressionist painter. He was particularly well known for his large scale Hard-edge paintings. After his first solo Abstract expressionist exhibition in 1959, Held's large-scale paintings of colourful, simple abstract geometric forms gained increasing recognition in America and Europe. In 1962, he was appointed to the Yale University Faculty Of Art (where he would teach until 1980). In 1965, the critic Irving Sandler curated the critically acclaimed Concrete Expressionism show at New York University featuring the work of painters Al Held and Knox Martin and the sculptors Ronald Bladen, George Sugarman and David Weinrib.
