Johannes Kepler (151-1630 AD)

Explanation:

It appears that none had postulated that planets move in non-circular (elliptical) orbits before affirmation by Johannes Kepler.

The scripts of Tycho Bravo (1473-1543) were quite useful to (Mathematics) Professor Kepler, for his prolonged research on circular orbits, before theorizing on elliptical orbits.

Much earlier, Nikolaus Copernicus (1473-1543 AD) had discredited the firm Earth-centric belief on orbits, by his heliocentric theory.
