Kepler
Kepler's 1st law states that the orbits of the planets around the sun and makes an ellipse. This is taught in astronomy.
Johannes Kepler
He showed that the planets traveled in elliptical orbits
Kepler
It was Kepler who discovered that the planets orbits are elliptical.
Kepler realised the planets orbits are not circles; they are ellipses.
Johannes Kepler, using measured planetary positional data provided by Tycho Brahe, showed that the orbits of the planets were ellipses ("flattened circles"), with the Sun at one focus of the eliipse.

No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.
Johannes Kepler determined that all planets have elliptical orbits.
