High Quality Content by WIKIPEDIA articles! Walt Wolfram (born February 15, 1941) is a sociolinguist at North Carolina State University, specializing in social and ethnic dialects of American English. He was one of the early pioneers in the study of urban African American English through his work in Detroit in 1969. Since the 1960s he has authored or co-authored 20 books and more than 250 articles on variation in American English. He was an active participant in the 1996 debate surrounding the Oakland Ebonics controversy, supporting the legitimacy of African American English as a systematic language system. In addition to African American English, Wolfram has written extensively about Appalachian English, Puerto Rican English, Lumbee English, and on many dialects of North Carolina, particularly of rural, isolated communities such as Ocracoke Island.
