Associate Professors: E. C. Barksdale; O. W. Johnston; H. Kraft; D. M. Popp; W. J. Sullivan III. Assistant Professor: H. H. Rennert. The department offers programs of study leading to M.A. and M.A.T. degrees in German. Areas of specializa- tion are German literature, Germanic linguistics and medieval literature. In addition, sufficient courses are available for a graduate minor in Russian.
