Borngen at Tautenburg. Philologist Konrad Duden (1829-1911), for a time a schoolmaster in Thuringia, was renowned for his trailblazing Orthographisches Wörterbuch der deutschen Sprache (1880). The "Duden", which has since gone through more than 20 revised editions, is the basis for uniform orthography in the German-speaking world.
