Well known in his lifetime as an astronomer, astrologer and alchemist, he has been described as "the first competent mind in modern astronomy to feel ardently the passion for exact empirical facts." His observations were some five times more accurate than the best available observations at the time. An heir to several of Denmark's principal noble families, he received

The first biography of Tycho Brahe, which was also the first full-length biography of any scientist, was written by Pierre Gassendi in 1654. In 1779, Tycho de Hoffmann wrote of Brahe's life in his history of the Brahe family. In 1913, Dreyer published Tycho Brahe's collected works, facilitating further research. Early modern scholarship on Tycho Brahe tended to see the shortcomings of his astronomical model, painting him as a mysticist recalcitrant in accepting the Copernican revolution, and valuing mostly his observations that allowed Kepler to formulate his laws of planetary movement.
