Contributed by Jacob Cartwright / In 1957, Clement Greenberg penned the essay “The Late Thirties in New York,” reflecting on years that were formative for both him and American art. He noted that during that decade “the big event, as I saw it, was the annual show of the American Abstract Artists group.” The artists who formed American Abstract Artists (AAA) first began meeting in 1936, in response to curators like MoMA director Alfred Barr, whose formulation of abstract art didn’t extend beyond the European continent. By 1937, AAA had begun organizing the regular New York City group shows that so impressed Greenberg.
