Science in his day

In our day

Tycho Brahe was the last major observational astronomer to work without a telescope; he used sextants and quadrants. Actually, in Astronomiæ Instauratæ Mechanica Brahe described more than a couple dozen astronomical instruments that he used or designed. Galileo Galilei introduced the use of telescopes into astronomy in 1610.

Tycho Brahe the man is known for his geo-heliocentric model of the solar system, and for a duel during which he lost his nose.
