	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). Both were autodidacts and thus had a similar background. As Bürgi did not understand Latin, Reimers translated Copernicus' "De Revolutionibus Orbium Coelestium" into German for Bürgi. A copy of the translation survived in Graz, it is thus called "Grazer Handschrift".
