He was also a familiar figure in plays by Ibsen, Chekhov, and Sophocles, and played Canon Chasuble in Oscar Wilde"s The Importance of Being Earnest. Eddison also made his mark in radio, in countless British Broadcasting Corporation dramas through the decades, with some of his last roles including Death in The Canterbury Tales and parts in an adaptation of Japanese Noh plays.
