In 1952 he was awarded a Ford Foundation Fellowship which assisted him in completing Richard III, which was published in 1955. It is for that work that he is best known. This work was a scholarly defence of the controversial monarch. It relied heavily on primary sources and made a significant contribution to the arguments for a favourable view of Richard. The work was critically very well received and was a runner-up for the National Book Award in 1956.
