Carl F. Hostetter

Carl F. Hostetter (born 1965) is a computer scientist at NASA's Goddard Space Flight Center, and a key figure of the Elvish Linguistic Fellowship. He is the author of numerous articles on Tolkienian linguistics, and the editor of two journals on the subject, Vinyar Tengwar (print) and Tengwestië (online). Hostetter has also contributed to various mailing-lists dedicated to Tolkien's languages, including Tolklang and Elfling, and founded two others, Lambengolmor in 2002 and Elfling-d. Together with Christopher Gilson, Arden R. Smith, Bill Welden, and Patrick H. Wynne (called by some the "Elfconners"), he has been engaged by Christopher Tolkien in the ordering, editing, and publishing of Tolkien's writings concerning his invented languages, which have been published as Parma Eldalamberon numbers 11 through 17 (and continuing) and in Vinyar Tengwar.

Together with Verlyn Flieger, he is the editor of Tolkien's Legendarium: Essays on The History of Middle Earth (Greenwood Press, 2000).
