Cowell, Brady Kynans, Kalvos Zondrios, Báthory Dénes, Orra Maussade, Don Johnson, Kerry Merritt, Calvin Dion, Enimtu Bemanyna) is a Hungarian-American author and composer.
Aside from music, he was an author during the first generation of personal computers (1979–85), and interviewed Bill Gates. His career in technology is evident in over 600 articles and books on the subject. He was involved in the post-Fluxus art movement (1973–78), and was also director of Vermont's Alliance of Independent Country Stores (2001–2010). Since 2010 he has been adjunct professor composition, theory, and music technology at Johnson State College.
Báthory lives in Northfield, Vermont. He claims to be a descendant of the Báthory family, a prominent central European clan during the Middle Ages but no proof of this can be found.
