Francis De Wolff
From Tardis Wiki, the free Doctor Who reference
Francis De Wolff (7 January 1913-18 April 1984) appeared in two Doctor Who stories: as Vasor in The Keys of Marinus and Agamemnon in The Myth Makers.
The commentators on BBC DVD: The Keys of Marinus quipped that the "modern equivalent" of De Wolff was Brian Blessed.
