James Bass Mullinger (1834 or 1843 – 22 November 1917), sometimes known by his pen name Theodorus, was a British author, historian, lecturer and scholar. A longtime university librarian and lecturer at St. John's College, Cambridge, Mullinger was the author of several books detailing the college's history and similar academic subjects. He was also a contributor to many periodicals of the Victorian era, most especially, Cambridge History of Modern Literature, the Dictionary of National Biography and Encyclopædia Britannica. His best known effort, History of the University of Cambridge Down to the Decline of the Platonists (1873), was a three-volume history of the university and was considered the definitive work on the subject at the turn of the 20th century. It is today considered a landmark publication in British university history. Source: Wikipedia (en)
