Theodor Schultz was a Moravian missionary in British Guiana at the turn of the nineteenth century. The Lokono ("Arawak") language manuscripts sent to the APS by him include both a grammatical treatise (organized upon the Latin model) ("Grammaticalische Sätze von der Aruwakkischen Sprache") and an extensive Lokono-German dictionary ("Aruwakkisch deutsches Wörterbuch, vermehrt 1803").
