Overview

Johannes Kepler ( December 27, 1571 - November 15, 1630) was a German mathematician, astronomer, and astrologer. A key figure in the 17th-century scientific revolution, he is best known for his laws of planetary motion, based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy. These works also provided one of the foundations for Isaac Newton's theory of universal gravitation.

Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually he was the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He was also a mathematics teacher in Linz, and an adviser to General Wallenstein. dditionally, he did fundamental work in the field of optics, invented an improved version of the refracting telescope (the Keplerian elescope), and was mentioned in the telescopic discoveries of his contemporary Galileo Galilei.
