The son of a non-juring clergyman, Walter Harte was a Tory friend of Pope, Young, and Elijah Fenton. He was educated at Marlborough School and St. Mary Hall Oxford (B.A. 1728, M.A. 1731), where he was Vice Principal and in much demand as a tutor. At the suggestion of Alexander Pope and Lord Lyttelton he was made tutor to Chesterfield's son, with whom he travelled on the Continent (1746-50). He was Canon of Windsor (1751). His major work was a History of Gustavus Adolphus (1759). The early biographies confuse him with another Harte (M.A. Pembroke Hall, 1720).
