William Hales

William Hales (April 8, 1747 - January 30, 1831) was an Irish mathematician, a professor of Oriental Languages and Divinity at Trinity College, Dublin, and in the latter half of his life a clergyman of the Church of Ireland, serving as rector of Killeshandra in County Cavan (from 1787), associated with the high church tendency. Hales notably wrote a three-volume series on Biblical chronology in relation to the chronologies of various nations of the world, later expanded to four-volumes in the second edition, as well as a number of mathematical treatises, including works in support of Newtonian theories (such as Newton's calculus, the Method of Fluxions).
