Johannes Kepler
Johannes Kepler determined that planets move in elliptical orbits around the sun in the early 17th century. His observations and mathematical calculations led to the formulation of his three laws of planetary motion.
Actually, it was the other way around. Johannes Kepler needed Tyco Brahe's detailed records of the paths of the planets in order to verify his theories regarding planetary motion. Tyco's observations were the most accurate at the time, so Kepler sought him out.
Kepler spent 20 years plotting the positions of the planet no he did not.
That was Tycho Brahe who lived on an island near Copenhagen and employed the great Johannes Kepler as his mathematician.

No, Tycho Brahe did, but Kepler just improved it and made it popular

Johannes Kepler studied under Tycho Brahe starting in 1600. After Brahe died one year later, Kepler took over his position as astronomer to the court in Prague.
