History
Konrad Duden
In 1872, Konrad Duden, headmaster of a Gymnasium in Schleiz, now in Thuringia, published a German dictionary called the Schleizer Duden, the first Duden. In 1880, he published the Vollständiges Orthographisches Wörterbuch der deutschen Sprache ; this seminal treatise was declared the official source for correct spelling in the administration of Prussia the same year. The first edition of the Duden contained 28,000 entries.
On the cover of the Duden, 25th Edition, Volume 1, these words are printed in red letters: Das umfassende Standardwerk auf der Grundlage der aktuellen amtlichen Regeln. This translates as: "The comprehensive standard reference based on the current official rules." The "current official rules" are the result of the German orthography reform of 1996.
