Bernard Berenson was an American art historian specializing in the Renaissance. He was a major figure in pioneering art attribution and therefore establishing the market for paintings by the "Old Masters". Berenson bequeathed his villa, I Tatti (near Florence), with its art collection and outstanding library, to Harvard to be administered as the Harvard Center for Italian Renaissance Studies. His books include The Drawings of the Florentine Painters (1903, 1938, 1961) and Italian Painters of the Renaissance (1952).
