Nicolaus Copernicus (1473 - 1543)
Nicolaus Copernicus (1473 - 1543) was a Polish astronomer, mathematician, physician and economist among other things. He is widely known for proposing the heliocentric model of the solar system which placed the sun at the centre. This heliocentric model challenged and eventually replaced the geocentric model that placed the earth at the centre and was an established dogma at the time.
