Tycho Brahe

Tycho Brahe (born Tyge Ottesen Brahe) (December 14, 1546 – October 24 1601) was a Danish nobleman known primarily for his work as an astronomer and an astrologer (the two were highly related in his day), as well as an alchemist. He was granted an estate on the island of Hven and the funding to build the Uraniborg, an early research institute, where he built large astronomical instruments and took many careful measurements. As an astronomer, Tycho worked to combine what he saw as the geometrical benefits of the Copernican system with the philosophical benefits of the Ptolemaic system into his own model of the universe, the Tychonian system. His best known assistant was Johannes Kepler, who would later use Tycho's astronomical information to develop his own theories of astronomy.
