Edwin Richfield

Edwin Richfield (11 September 1921-2 August 1990 ) appeared in two Doctor Who stories: as Captain John Hart in The Sea Devils and Mestor in The Twin Dilemma.

Richfield's best known role was probably Steve Gardiner, the titular "odd man" of the title, in. Richfield played the role from series two onwards, replacing Geoffrey Toone, who had played Gardiner in the first season.

He also appeared as Inspector Mornay in ITC's, Mr Pomeroy in and Frank Chapman in. He was also the only actor besides Patrick Macnee to appear in all six seasons of The Avengers, playing different characters each time.
