Franz Friedrich Roger Wilmans (18 July 1812, in Bielefeld – 28 January 1881, in Münster) was a German historian and archivist.
From 1832 he studied philology and history at the University of Berlin, receiving his doctorate in 1835 with a dissertation on Cassius Dio, De Dionis Cassii fontibus et auctoritate. Afterwards, he worked as a schoolteacher at the Cadet Corps and Joachimsthal Gymnasium in Berlin. In 1851 he succeeded Heinrich August Erhard as director of the provincial archives in Münster, a position he maintained up until his death in 1881.[1]
