Carl Friedrich Roewer

Carl Friedrich Roewer (12 October 1881, Neustrelitz - 17 June 1963) was a German arachnologist. He concentrated on harvestmen, where he described almost a third (2,260) of today's known species, but also almost 700 taxa of spiders and numerous Solifugae.

From 1933 on, he was the second director of the Ubersee-Museum in Bremen, Germany.

The Senckenbergische Naturforschende Gesellschaft bought his extensive collection (including type material from other arachnologists such as L. Koch, Eugene Simon, Thorell, Philipp Bertkau and Friedrich Dahl) and his private library. Some of his specimens are also in the Museum fur Naturkunde Berlin.
