Johannes Kepler

Johannes Kepler was a German astronomer and mathematician, born in the imperial city of Weil der Stadt, who discovered the three laws of planetary motion. He served as imperial mathematician in Prague and published the Rudolphine Tables in 1627. In 1628 Albrecht von Wallenstein brought him to Żagań in Silesia, where he set up a printing press; he died in Regensburg two years later.
