Barrow, Isaac, 1630–77, English mathematician and theologian. His method of finding tangents prefigured the differential calculus developed by Isaac Newton. He was professor of mathematics at Cambridge from 1663 to 1669 and was succeeded by Newton. Barrow became master of Trinity College in 1672 and vice chancellor of Cambridge in 1675. His theological works were edited by Alexander Napier (1859) and his mathematical works by William Whewell (1860).
