Arthur Ludwich

Constantin Hermann Arthur Ludwich (18 May 1840, Lyck in East Prussia – 12 November 1920, Königsberg) was a German classical philologist who specialized in Homeric studies. He is remembered for his observations involving the metric and prosody of Homer, for his edition of the Dionysiaca by Nonnus, and for coining the term "Viermännerkommentar" (i.e. "Four-Men Commentary", being Aristonicus, Didymus, Herodian and Nicanor) to define a lost ancient commentary to Homer's Iliad, survived in fragments prominently in the A-class of marginals.

He studied theology and classical philology at the University of Königsberg, where his instructors included Karl Lehrs and Ludwig Friedländer. In 1874–75 he conducted Homeric research in Italy, and during the following year, became an associate professor at the University of Breslau. In 1878 he succeeded Lehrs as professor of Greek philology at Königsberg.
