Isaac Newton was born on December 25, 1642 in Woolsthorpe, Lincolnshire, England. He showed signs of an exceptional intelligence and solitary personality in grammar school, and he was admitted to the prestigious Trinity College in Cambridge in June 1661. Newton was from the beginning an independent thinker, moving beyond the standard curriculum, which focused mainly on classical Aristotelian philosophy, to study Descartes. Working almost entirely in isolation, Newton laid the groundwork of his theory of infinitesimal calculus, binomial expansion, laws of motion, theory of color, and theory of universal gravitation between 1664 and 1666.
In October 1669 he was named Lucasian professor of mathematics, but lectured very little in later years. Soon after, he designed and constructed the first reflecting telescope, which led to his election to the Royal Society in January of 1672.
Newton composed his masterpiece, the Philosophiae Naturalis Principia Mathematica (usually referred to as simply Principia) between 1684 and 1686. Edmond Halley, of comet fame, helped it into publication in 1687. Newton’s key insight that the same force of gravity felt on Earth also held the planets in their orbits around the Sun was developed there in detail. This provided a framework for the Laws of planetary motion discovered by Kepler, as well as many other phenomena including the orbits of comets. Newton also made numerous discoveries in the field of optics, especially with light and colors. His groundbreaking studies of the diffusion of light by a glass prism were begun as early as 1665 and described in full in his 1704 Opticks.
Newton was jealous of his ideas and inclined to resist contact with other European scientists. His difficult personality and territorial led to disputes with, for example, Robert Hooke and Gottfriend Wilhelm Leibniz. He became increasingly political later in life, serving somewhat dictatorially as the president of the Royal Society from 1703 until his death in 1727. In 1705 he was knighted for his achievements.
Isaac Newton died in Kensington on March 20, 1727, and was buried in Westminster Abbey.
