EADMER or EDMER (c. Io6o—I I24), English historian and ecclesiastic, was probably of English parentage. At the monastery of Christ Church, Canterbury, he met Anselm, to whom he served as assistant when Anselm became archbishop of Canterbury in 1093. In 1120 he was nominated archbishop of St. Andrew's, but the Scots refused to recognize the authority of Canterbury. He died probably in 1124. His most important work is the Historiae Novorum, dealing with the history of England, mainly ecclesias tical, between 1 o66 and 1122. It was first edited by John Selden in 1623. Together with his Vita Anselmi (first printed in Ant werp in 1551) it was edited by M. Rule for the Rolls Series (London, 1884). He also wrote lives of St. Dunstan and St. Os wald which are printed in Henry Wharton's Anglia Sacra part 2, (1691), which has also a list of his works. Most of his mss. are in the library of Corpus Christi college, Cambridge.
