Rudolf von Roth (1821-1895) was a prominent German philologist. Educated at Tübingen and Berlin, he continued his studies in Paris and London, and in 1848 received the appointment of extraordinary professor of Oriental languages in Tübingen University, becoming full professor and principal librarian in 1856. In this Festgruss, forty four of his colleagues and students presented him papers on various topics on the occasion of his Doctor-Jubiläum. They included luminaries like Theodor Nöldeke, William D. Whitney, Edward V. Arnold, and others. The topics discussed are mostly philological covering a wide range of eastern languages, both Semitic and Indic.
