Johannes Kepler - University of Chicago
Perhaps the most important seventeenth-century astronomer, Johannes Kepler's work transformed both our knowledge of the heavens and the enterprise of astronomy itself. Kepler adopted Copernican's sun-centered universe as a young man, before using Tycho Brahe's extremely accurate observations to overthrow a tradition of astronomical theorising ...
