Nicolaus Reimers

From 1585 to 1586 he was employed as a private tutor in Pomerania and from 1586 to 1587, Reimers stayed at the court of William IV, Landgrave of Hesse-Kassel in Kassel, where he met Swiss instrument maker Jost Bürgi (1552–1632).

History has sided with Ursus on the later issue, and he had stated that the technique was the invention of Paul Wittich and Jost Bürgi.

Ursus objected to the Copernican model as it violated the Aristotelian principle of not allowing more than one natural movement by a body.

Johannes Kepler committed a faux pas early in his career by sending a laudatory letter to Reimers while seeking the patronage of Tycho.

However Kepler discovered Tycho had posited intersecting Martian and Solar orbits because he had mistakenly concluded from his data that at opposition Mars was closer to the Earth than the Sun was.
