Dr Gilbert Kymer (d. 1463) was a leading royal physician, scholar, cleric and university administrator of the first half of the 15th century. He was physician to Henry V & VI, and principally to Humphrey Duke of Gloucester, for whom he wrote an extensive Dietarium. He collected medical books and facilitated their translation, and helped to set up Duke Humfrey’s library at Oxford. He became Dean of Salisbury, and for 11 years was Chancellor of the University of Oxford.
