3691 Bede           Discovered 1982 Mar. 29 by L. E. Gonzalez at Cerro El Roble.
The Venerable Bede (c. 672-735), the "Father of English History" who popularized the A.D. reckoning of years, compiled a history of England since the time of Caesar. The name follows a suggestion by B. Hafferty in the BBC Word of Mouth competition in this centenary year of St. Bede's School, Bradford, West Yorkshire.
