In 1473, Copernicus was born in Torun, Royal Prussia, also know as the Kingdom of Poland. (OConnor and Robertson) His polish name was Mikolaj Kopernik. (Weisstein) When he was ten his father, an influential entrepreneur and well liked citizen of Torun, died. Information about Copernicus mother is scarce. Little is known about her except that she passed away before Copernicus father did, and she was the daughter of a wealthy merchant. After him and his three other siblings were orphaned, Copernicus uncle raised him and his brother and two sisters. (OConnor and Robertson) Copernicus went on to attend Cracow University where he studied optics and mathematics. Then he studied canon law, or the laws that govern the affairs of the Christian church, in Bologna. After finishing his schooling in Italy, he was appointed to the position of canon in the Frauenburg cathedral thanks to the influence of his uncle. The position that Copernicus held at the cathedral allowed him to associate with a powerful circle of colleagues. (Landry)

Incomplete versions of his prose were distributed among other astronomers who were considering his theories, but Copernicus was in no rush to publish his work. This time, hesitation to publish his book was not out of fear of the churchs reaction. More accurately, his reluctance was because he was a perfectionist. Even after spending roughly three decades on his book, he never really felt his dissertation was complete. If it had not been for George Rheticus, a twenty-five year old German Mathematician, Copernicus work may have never reached the printing press. (Landry)
Rheticus became enamored with Copernicus and sought him out after reading one of his essays. Rheticus paid a visit to Copernicus home, he anticipated
