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".
