Johannes Kepler

Johannes Kepler was a German mathematician and astronomer, and a leading exponent of the Copernican heliocentric system. He is most famous for his laws of planetary motion. A contemporary of Galileo, he succeeded Tycho Brahe as imperial mathematician in Prague, and in 1609 he established the geometrical basis of the laws of planetary motion using Brahe’s observations. Kepler also carried out research on cosmic harmonies, celestial physics and optics.
In September 2015, Dr A.E.L. Davis FRAS and Dr J.V. Field FRAS curated a selection of some of Kepler’s most important works for display in the Library exhibition cases. This webpage is a record of the exhibition.
