Tycho Brahe

Tycho Brahe (1546–1601) was a Danish astronomer and nobleman who made significant contributions to the field of astronomy. He is best known for his accurate and comprehensive astronomical observations. Brahe built and operated a series of observatories, most notably Uraniborg on the island of Hven, where he conducted extensive measurements of celestial bodies without the aid of a telescope, which had not yet been invented.
