Ivor Donald Dean (21 December 1917 – 10 August 1974) was a British stage, film and television actor. With his lugubrious demeanour he was often cast as world-weary police officers or butlers, and it is for the role of Chief Inspector Claud Eustace Teal in the 1960s series The Saint, opposite Roger Moore, that he is best known.Dean played Teal for almost the entire run of the series, except three instances in early episodes where other actors were used. It was on the third occasion, in an episode called Starring The Saint which featured Dean in another role, that the producers saw the ideal actor for the part.
