Death of Nicolaus Copernicus

24 May 1543

Nicolaus Copernicus died on 24 May 1543 in Frombork, aged 70. A Polish astronomer and mathematician, Copernicus studied in Kraków and in Italy, and spent most of his life as a canon of the cathedral at Frombork. He proposed a heliocentric model of the Solar System, in which the Earth and the other planets revolve around the Sun, and the Earth rotates daily on its axis, in contrast to the geocentric system of Ptolemy. He worked out his theory in the 1510s but published it only in 1543, in On the Revolutions of the Heavenly Spheres, the year he died. His work began the Scientific Revolution. He was also a physician, administrator and economist.
