48458 Merian           Discovered 1991 Sept. 13 by F. Börngen and L. D. Schmadel at Tautenburg.
Swiss engraver, etcher and book dealer Matthäus Merian (1593-1650) and his sons published more than 2000 detailed town views and city maps in the Topographia Germaniae at Frankfurt-am-Main beginning in 1642. These maps are of paramount importance in the area's cultural history.
