Sir Clarence Henry Kennett Marten KCVO (28 October 1872 – 11 December 1948) was the Provost of Eton and the private tutor of Queen Elizabeth II.
In 1912, he published The Groundwork of British History with his co-author, George Townsend Warner, which became "one of the most used school textbooks of the first half of the twentieth century".
[1] With E. H. Carter,[a] he wrote a school textbook for younger children, in several volumes, titled simply "Histories".
In 1925, Marten narrowly missed becoming Master of Magdalene College, in Cambridge, when he was recommended to the hereditary Visitor of Magdalene, Lord Braybrooke as a possible candidate, but the College Fellows opposed the appointment, preferring another candidate, A. S. Ramsey.
[1][4] He was appointed Knight Commander of the Royal Victorian Order in the 1945 New Year Honours,[5] and received the accolade from King George VI on 4 March 1945, on the steps of Eton College Chapel.
