Henry Francis Pelham, FSA, FBA (10 September 1846 in Bergh Apton, Norfolk – 13 February 1907) was an English scholar and historian. He was Camden Professor of Ancient History at the University of Oxford from 1889 to 1907, and was also President of Trinity College, Oxford from 1897 to 1907.
He was grandson of Thomas Pelham, 2nd Earl of Chichester, and eldest of the five children of John Thomas Pelham, bishop of Norwich, and Henrietta, second daughter of Thomas William Tatton of Wythenshawe Hall, Cheshire. Of his three brothers, John Barrington became vicar of Thundridge in 1908, and Sidney archdeacon of Norfolk in 1901. Pelham was born on 19 September 1846 at Bergh Apton, then his father's parish. Entering Harrow (Westcott's house) in May 1860, he moved rapidly up the school, and left in December 1864. Next year he won an open classical scholarship at Trinity College, Oxford, matriculating on 22 April 1865; he came into residence in October. At Oxford he took 'first classes' in honour classical moderations and in literæ humaniores, was elected a fellow of Exeter College in 1869, and graduated B.A. in the same year. In 1870, he won the chancellor's English essay prize with a dissertation on the reciprocal influence of national character and national language. He worked continuously as classical tutor and lecturer at Exeter College from 1870 till 1889. He was elected by his college proctor of the university in 1879. Losing his fellowship on his marriage in 1873, he was re-elected in 1882, under the statutes of the second university commission.
From school onwards his principal subject was ancient and more particularly Roman history. He soon began to publish articles on this theme (first in Journal of Philology, 1876), while his lectures, which (under the system then growing up) were open to members of other colleges besides Exeter, attracted increasingly large audiences; he also planned, with the Clarendon Press, a detailed History of the Roman Empire, which he was not destined to carry out. In 1887, he succeeded W. W. Capes as 'common fund reader' in ancient history, and in 1889 he became Camden Professor of Ancient History in succession to George Rawlinson, a post to which a fellowship at Brasenose College is attached. As professor he developed the lectures and teaching which he had been giving as college tutor and reader, and attracted even larger audiences.
