Nicolaus Copernicus

The discoveries he made sparked a new school of astronomical thought, and became the basis for theories made by Galileo, Newton, and Kepler. The work they did helped to perfect his original theory.

Copernicus had three siblings, of whom only one did not become committed to the church – both he and his brother became clergymen, and one of his sisters became a nun.

Nicolaus was barely ten years old when his father died, in 1483. He was then cared for by his maternal uncle, who would become Bishop of Warmia. His uncle paid for his education at the ‘St. John’ parochial school.

He left the St. John school in 1491 to attend the ‘University of Krakow’, where he studied mathematics, drawings, perspective, and the classics. This is where he developed his love for astronomy, having attended lectures given by a prominent Polish astronomer, and began studying the stars and planets from his home.

In 1497, he enrolled in the ‘University of Bologna’ to study canon law. He also joined the ‘Chapter of Warmia’ and received his first appointment as a canon scholar.

Nicolaus traveled to Rome in 1500 to attend ‘The Jubilee’, where he gave lectures on mathematics. These were attended by George Rheticus, who would later assist him in publishing his greatest work. The next year he renewed his leave of absence so that he could have two more years of study, which he used to study medicine at Padua while he continued studying law.

He received another appointment as a canon scholar for the ‘Holy Cross Church’ in Wroclaw, in 1503. In the same year he was awarded his doctorate in canonical law. After completing his studies he returned to Warmia to work for the church.

Copernicus sent out his first work, ‘Commentariolus’ (Little Commentary), as a series of letters, in 1507. Here he presented the first versions of the heliocentric theory. He was also appointed by the Chapter to be the private physician to the Bishop.

In 1509, he left the Bishop and returned to Frombork. There he became more involved in political affairs, drawing a map of Warmia and the western borders of Royal Prussia for the King’s Council and swearing his allegiance to the King.

Copernicus completed the manuscript for ‘De revolutionibus’ many years before he allowed it to be published. For over a decade he circulated the theory in a series of letters to European scholars and worked painstakingly on revisions. It was only in 1543 that the book was published in its entirety in Nuremburg.
