Born in England, he began his career when he was recruited as a professor of moral philosophy for the
College of William & Mary,
Williamsburg,
Virginia. He arrived in 1770. Well-connected there, he became a friend of
Thomas Jefferson, who acquired some of his library. He clashed though in public debate with
Robert Carter Nicholas, Sr. and
John Page, and failed to become rector of
Bruton Parish Church. In 1775 he went back to England, as a
Loyalist taking leave from the college but never returning; he was a supporter of
John Murray, 4th Earl of Dunmore, Virginia's governor, and with his colleague
Thomas Gwatkin had been subject to intimidation by armed men. He obtained an assistant-mastership at
Harrow School, and soon afterwards received a
curacy at
Northall in
Middlesex. In 1778 he was elected a fellow of the
Society of Antiquaries, and four years later he was presented to the living of
Rendlesham in
Suffolk. He continued to spend the greater part of his time at Harrow. Henley maintained an extensive correspondence on antiquarian and classical subjects with
Michael Tyson,
Richard Gough,
Dawson Turner,
Thomas Percy, and other scholars of the time. In 1805 he was appointed principal of the newly established
East India Company College at
Hertford. He resigned this post in January 1815, and died on 29 December of the same year. He married in 1780 a daughter of Thomas Figgins of
Chippenham,
Wiltshire. ==Works==
