Vuk Stefanović Karadžić was a Serbian philologist, anthropologist and linguist. He was one of the most important reformers of the modern Serbian language. For his collection and preservation of Serbian folktales, Encyclopædia Britannica labelled Karadžić "the father of Serbian folk-literature scholarship." He was also the author of the first Serbian dictionary in the new reformed language. In addition, he translated the New Testament into the reformed form of the Serbian spelling and language.
