Today, when a painting by a living American artist fetches seventeen million dollars at auction, as a picture by Jasper Johns did last year, or when hundreds of people stand in line to get into a museum, as they did for the retrospectives of Edward Hopper, Willem de Kooning, and Georgia O’Keeffe, it is almost impossible to imagine the hostility and suspicion long encountered by American artists. In the early years of this century, a painter of independent or nonconformist leanings was a pariah. Thomas Eakins once replied to a biographical query, “My honors are misunderstanding, persecution, and neglect. …” New York was more tolerant than Eakins’s Philadelphia, but even there the art world was controlled by conservatives who wrote off the homegrown talent as insignificant. Fewer than six commercial galleries sold or showed the work of living Americans, and only two were willing to gamble on anything out of the ordinary. John Sloan was not wrong when he concluded, “Artists, in a frontier society like ours, are like cockroaches in kitchens—not wanted, not encouraged but nevertheless they remain.”
