Johannes Kepler

(December 27, 1571 – November 15, 1630)

Johannes Kepler a key figure in the scientific revolution, was a Lutheran mathematician, astrologer, and astronomer. He is best known for his laws of planetary motion, based on his Astronomia nova, Harmonice Mundi and the textbook Epitome of Copernican Astronomy.

Through his career Kepler was a mathematics teacher at a Graz seminary school (later the University of Graz), an assistant to Tycho Brahe, court mathematician to Emperor Rudolf II, mathematics teacher in Linz, and court astrologer to General Wallenstein. He also did fundamental work in the field of optics and helped to legitimate the telescopic discoveries of his contemporary Galileo Galilei.

He is sometimes referred to as "the first theoretical astrophysicist", although Carl Sagan also referred to him as the last scientific astrologer.
