Isaac Barrow was an eminent English mathematician and divine. He was born in 1630 at London and died in 1677. He studied at the Charterhouse and at Trinity College, Cambridge, of which he became a fellow in 1649. After a course of medical studies he turned to divinity, mathematics, and astronomy, graduated anew at Oxford in 1652, and, failing to obtain the Cambridge Greek professorship, went abroad. In 1659 he was ordained; in 1660 elected Greek professor at Cambridge; in 1662 professor of geometry in Gresham College; and in 1663 Lucasian professor of mathematics at Cambridge, a post which he resigned to Isaac Newton in 1669. In 1670 he was created D.D., in 1672 master of Trinity College, and in 1675 vice-chancellor of Cambridge University. His principal mathematical works (written in Latin) were (an edition of which was edited by Whewell): Euclidis Elementa, 1655; Euclidis Data, 1657; Mathematics Lectiones, 1664-66; Lectiones Opticse, 1669; Lectiones Geometricse, 1670; Archimedis Opera; Apollonii Conicorum lib. iv.; Theodosii Spherica, 1675. All his English works, which are theological, were left in manuscripts and published by Dr. Tillotson in 1685. As a mathematician Barrow was deemed inferior only to Isaac Newton.
