Peter Charanis (1908 – 23 March 1985), born Panagiotis Charanis (Greek: Παναγιώτης Χαρανής ), was a Greece-born American scholar of Byzantium and the Voorhees Professor of History at Rutgers University. Dr. Charanis was long associated with the Dumbarton Oaks research library.
Peter Charanis got his doctorate before 1985.
Peter Charanis died in March of 1985, but was a professor prior to his death, so he must have earned his doctorate in one of the years before. I think it was difficult for the system because the context did not specifically mention that he had a doctorate (only that he was Dr. Charanis).
