Arie de Jong, Dutch linguist and author (died 1957)

Arie de Jong was a Dutch enthusiast and reformer of the constructed language Volapük by Johann Martin Schleyer, with whose help the Volapük movement gained new strength in the Netherlands. He not only revised Volapük, but also began Volapükaklub Valemik Nedänik and founded Diläd valemik Feda Volapükaklubas. He also founded and edited Volapükagased pro Nedänapükans, an independent newspaper in Volapük, which ran for thirty-one years (1932–1963). He wrote Gramat Volapüka, a grammar of the language completely in Volapük, and a German-Volapük dictionary, Wörterbuch der Weltsprache. He translated the New Testament into Volapük from Greek, as well as many other pieces of literature. Arie de Jong is justly considered the most important Volapükist of a new age of Volapük history.
