Edward James Rapson FBA (12 May 1861 – 3 October 1937) was a British numismatist, philologist and professor of Sanskrit at the University of Cambridge. He was a fellow of St. John's College. Rapson died following a sudden collapse at dinner at St. John's.
Rapson was born at Leicester, the son of the Rev. Edward Rapson, later vicar of West Bradley, Somerset, where Rapson spent much of his childhood. He attended the Hereford Cathedral School and then St John's College, University of Cambridge, where he was elected a classical foundation scholar in 1883. He won the Brotherton Sanskrit Prize in 1884 and the La Bas Prize in 1886.
In 1887 Rapson was appointed assistant in the Department of Coins and Medals at the British Museum, and also elected a fellow of St. John's College. From 1903 he was Professor of Sanskrit at University College, London. In 1906 he left the British Museum and was appointed Professor of Sanskrit at St. John's. His application included eighteen testimonials. Following his successful appointment he remained there until his retirement in 1936 when he was succeeded by H.W. Bailey. His connection with the British Museum continued throughout his career and he assisted in the preparation of the Aurel Stein Collection.
Rapson edited the first volume of The Cambridge History of India, "Ancient India", where his expertise in coins was put to good use. The Times noted in their review of the volume that coin evidence provided some of the only sources for the earliest rulers mentioned, there being in many cases no surviving written sources. Rapson spent time on secondment from the College at the Department of Coins and Medals of the British Museum, where he was Assistant Keeper of Coins and Medals and was reckoned to have an uncanny ability to be able to identify ancient coins merely by feel.
