Areas of specialization: Medieval German Literature; German literature of the 16th and 17th Centuries; Satire and Polemic. Professor Walker's research and teaching focussed on literary expressions of religious discontent and social change during the period from the late 15th through the 17th centuries. Emphasizing texts, contexts and continuity, his research covered sermons, polemical treatises, satirical popular literature (Schwänke, Fastnachtspiele, Anekdoten), religious and secular drama, and the interrelatedness of literary history and social history. Dr. Walker’s most recent publication is an English translation of the Arminius Dialogue of Ulrich von Hutten (1488-1523) by Peter Lang Verlag. He is currently preparing a translation of Gustav Adolph Graf von Götzen’s Durch Afrika von Ost nach West, an extensive and detailed report of an expedition in 1894-95 from the east coast of Africa to the German East Africa colony and the region known today as Rwanda.
