Tycho Brahe may not be as famous as Galileo
, but in some circles he's considered the father of modern astronomy. He spent much of his life compiling the world's first truly accurate and complete set of astronomical tables -- all before the invention of the telescope. In 1628 Kepler published the Rudolphine Tables
, a list of remarkably accurate logarithmic astronomical tables based on Brahe's observations and Kepler's subsequent analysis. Brahe's assistant, Johannes Kepler
, later used the tables to deduce the laws of planetary motion.
