Gradually his literary successes began to mount. He won the Pulitzer Prize three times in the 1920s, and he was described as "more artful than Hardy and more coy than Frost and a brilliant sonneteer". During the last 20 years of his life he became a regular summer resident at the MacDowell Colony in New Hampshire, where several women made him the object of their devoted attention. Robinson and artist Elizabeth Sparhawk-Jones visited MacDowell at the same times over a cumulative total of ten years. They had a romantic relationship in which she was in love with him, devoted to him and understood him, and was relaxed in her approach with him. He called her Sparhawk and was courteous towards her. They had a relationship that D. H. Tracy described as "courtly, quiet, and intense". She described him as a charming, sensitive, and emotionally grounded man with high moral values.
