John Keill

Born 1 Dec 1671; died 31 Aug 1721 at age 49.Scottish mathematician and natural philosopher, who was a major proponent of Newton's theories. He began his university education at Edinburgh under David Gregory, whom he followed to Oxford, where Keill lectured on Newton's work, and eventually became professor of astronomy. In his book, An Examination of Dr. Burnett's Theory of the Earth (1698), Keill applied Newtonian principles challenging Burnett's unsupportable speculations on Earth's formation. In 1701, Keill published Introductio ad Veram Physicam, which was the first series of experimental lectures and provided a clear and influential introduction to Isaac Newton's Principia. He supported Newton against priority claims by Leibnitz for the invention of calculus. (James Keill was his younger brother.)«
