Nicolaus Copernicus
Once upon a time, people thought that the Earth, not the sun, was the center of the universe. Copernicus was the one who led us in the right direction. Born in 1473, he created a heliocentric solar system model that withstood the test of time. Originally from Poland, he wandered all over Europe.
What Nicolaus Copernicus Really Looked Like
Old renditions of him do not do him any justice. He is often portrayed as a hollowed and gaunt man. With modern technology, they managed to show us what he looked like when he was still alive. However, Copernicus still looks rather miserable here. Maybe that is what all geniuses are like.
