Johannes Kepler was an important mathematician whose advances in mathematics include discovering the elliptical orbits of the planets and describing laws of planetary motion. All this from humble beginnings in a quaint German town. Kepler lived from 1571 to 1630, during which he was a student, teacher, imperial mathematician, and had strong devotion to the church.
