Serbian philologist and linguist who was the major reformer of the Serbian language. He deserves, perhaps, for his collections of songs, fairy tales, and riddles, to be called the father of the study of Serbian folklore. He was also the author of the first Serbian dictionary in his new reformed language. In addition, he translated the New Testament into the reformed form of the Serbian spelling and language. He was well known abroad and familiar to Jacob Grimm, Johann Wolfgang von Goethe and historian Leopold von Ranke. Vuk was the primary source for Ranke's Serbische Revoluzion ("Serbian Revolution"), written in 1829.
