SIR PAUL NEILE is the only one of the twelve founder members of the Royal Society of whom there is no record in the Dictionary of National Biography. We should know little of his activities were it not for the entries in the Journal Books of the Society and the references to him by Evelyn and in Huygens, correspondence. He was the son of Richard Neile, Archbishop of York and the father of William Neile, F.R.S. (1637-1670), a brilliant mathematician whose early death was a great loss to the Society. Paul Neile was born at Westminster in 1613 and was admitted as a Fellow Commoner to Pembroke College, Cambridge, in 1627, at the age of 14. He was one of the Ushers of the Privy Chamber to Charles I and was knighted in 1633, when he is described as of Sutton Bonvill, Yorks, N.R. He was M.P. for Ripon in the Short Parliament of 1640. He married Elizabeth, daughter of Gabriel Clark, D.D., Archdeacon of Durham, and their eldest son William was born at York in 1637.
