William Walker (1623 â 1 August 1684) was an English schoolmaster and grammarian.
Walker was born in Lincoln, England in 1623, and educated at the public school there. He proceeded to Trinity College, Cambridge, where he took his degree. He taught for some time at a private school at Fiskerton, Nottinghamshire, was headmaster of Louth grammar school, and subsequently of Grantham grammar school, where he is erroneously said to have had Sir Isaac Newton as a pupil. Newton, however, had left the Grantham grammar school while Walker's predecessor, Mr. Stokes, was still at its head, but there existed a friendship of some intimacy between the two when Walker was vicar of Colsterworth, after he had left Grantham. Walker died on 1 August 1684.
