Nicolaus Copernicus became a canon in 1497 when he was appointed to the position at the Frombork Cathedral in Warmia, Poland. This role allowed him to focus on his astronomical studies while also fulfilling his duties as a church official. His work as a canon also provided him with the resources and time to develop his heliocentric model of the solar system, which he famously published in "De revolutionibus orbium coelestium" in 1543.
