Nicolaus Copernicus was a mathematician and astronomer who proposed the theory that the sun was stationary in the center of the universe and the earth revolved around it. He lived from 1473-1543.
At the time, his theory about the sun was controversial; nevertheless, it was the start of a change in the way that the world was viewed. Since his death, Copernicus has come to be seen as the initiator of the scientific revolution.
