content: Denison Bingham Hull (1897-1988) was a Chicago architect who lost his hearing and, dissatis-fied with the hearing aids on the market, decided to design his own. The Otarion, unveiled in 1940, was small, inexpensive, relatively light weight, and contained four radio tubes. In 1954, Otarion was purchased by Leland E. Rosemond and moved to Dobbs Ferry, N.Y.
