Best Known For

Nicholas Copernicus was a Polish astronomer who proposed that the planets rotate around the Sun and not vice versa.

Synopsis

Born on February 19, 1473, in Toru, Poland, Nicholas Copernicus proposed the idea of a heliocentric (sun centered) solar system and the idea that the Earth, besides orbiting the Sun annually, also turns once daily on its own axis. Copernicus's theory had important consequences for later scientific thinkers, including such major figures as Galileo, Kepler, Descartes, and Newton.

(born Feb. 19, 1473, Toru, Pol.—died May 24, 1543, Frauenburg, East Prussia [now Frombork, Pol.]) Polish astronomer who proposed that the planets have the Sun as the fixed point to which their motions are to be referred; that the Earth is a planet which, besides orbiting the Sun annually, also turns once daily on its own axis; and that very slow, long-term changes in the direction of this axis account for the precession of the equinoxes. This representation of the heavens is usually called the heliocentric, or “Sun-centred,” system—derived from the Greek helios, meaning “Sun.” Copernicus's theory had important consequences for later thinkers of the scientific revolution, including such major figures as Galileo, Kepler, Descartes, and Newton. Copernicus probably hit upon his main idea sometime between 1508 and 1514, and during those years he wrote a manuscript usually called the Commentariolus (“Little Commentary”). However, the book that contains the final version of his theory, De revolutionibus orbium coelestium libri vi (“Six Books Concerning the Revolutions of the Heavenly Orbs”), did not appear in print until 1543, the year of his death.

Early life and education

Certain facts about Copernicus's early life are well established, although a biography written by his ardent disciple Georg Joachim Rheticus (1514–74) is unfortunately lost. According to a later horoscope, Nicolaus Copernicus was born on February 19, 1473, in Toru, a city in north-central Poland on the Vistula River south of the major Baltic seaport of Gdask. His father, Nicolaus, was a well-to-do merchant, and his mother, Barbara Watzenrode, also came from a leading merchant family. Nicolaus was the youngest of four children. After his father's death, sometime between 1483 and 1485, his mother's brother Lucas Watzenrode (1447–1512) took his nephew under his protection. Watzenrode, soon to be bishop of the chapter of Varmia (Warmia), saw to young Nicolaus's education and his future career as a church canon.

Between 1491 and about 1494 Copernicus studied liberal arts—including astronomy and astrology—at the University of Cracow (Kraków). Like many students of his time, however, he left before completing his degree, resuming his studies in Italy at the University of Bologna, where his uncle had obtained a doctorate in canon law in 1473. The Bologna period (1496–1500) was short but significant. For a time Copernicus lived in the same house as the principal astronomer at the university, Domenico Maria de Novara (Latin: Domenicus Maria Novaria Ferrariensis; 1454–1504). Novara had the responsibility of issuing annual astrological prognostications for the city, forecasts that included all social groups but gave special attention to the fate of the Italian princes and their enemies. Copernicus, as is known from Rheticus, was “assistant and witness” to some of Novara's observations, and his involvement with the production of the annual forecasts means that he
