Redfield is considered one of the most important figures of the New Hope School of Pennsylvania Impressionism. “Critics viewed his "fine, manly art of landscape painting" as a "rejuvenating force" in the "much-needed Renaissance of American art." ... Redfield’s artistic method and personal manner—his painterly "virility" and rugged communication with nature—[are seen] as signifying his Americanness.”
