Frank Dudley Foster (7 August 1924 – 8 January 1973) was an English actor who regularly appeared in television roles.
Foster was born in Brighouse, West Riding of Yorkshire. His family had established links with the theatre; and a brother and sister also appeared on the stage. They were the children of Frank Geden Foster, a civil engineer, who was to die exactly a week before his son. Educated at Pocklington School, and following service as a navigator in the RAF, Dudley Foster studied chemistry at the University of Leeds. In 1948 he joined the recently formed Bradford Civic Playhouse Theatre School and after turning professional, spent several successful years with northern repertory companies. From the later 1950s into the 1960s, he was a member of Joan Littlewood's Theatre Workshop based at London's Theatre Royal Stratford East. In her autobiography, Joan's Book, Littlewood recalled that Foster had a wealthy father who financed some of the troupe's productions.
On television, he appeared often in villainous roles in such series as Danger Man, The Saint, The Avengers ("The Hour That Never Was", 1965), "Something Nasty in The Nursery" (1967) and "Wish You Were Here" (1969 – playing a perfect mannered yet sinister hotel manager in a parody of the TV series The Prisoner), Randall and Hopkirk (Deceased) (1969 in the episode "All Work and No Pay", as villain George Foster),
The Persuaders! (1971 in the episode "Anyone Can Play", in which he played the spy network paymaster Heather), Catweazle ("The Ghost Hunters as Hector Kenley", 1971), Public Eye (1972 episode "Mrs Podmore's Cat", as Major Thursby-Byers),  Steptoe and Son (four episodes: playing Martin, the oily 'card shark' in "Full House", the supercilious Labour Party rep in "My Old Man's A Tory", the pained police inspector in "Robbery with Violence", and uncredited as the car salesman in "The Colour Problem") and Doctor Who ("The Space Pirates", 1969).
In Z-Cars, in the early 1960s, he played a police detective, Inspector (later Superintendent) Dunn. He was also in Bat Out of Hell (1966), a BBC serial by Francis Durbridge, playing a formidable police inspector, and starred with John Bird in the office comedy series If It Moves File It (1970) by Troy Kennedy Martin. He occasionally appeared in films: in The Little Ones as Superintendent Carter alongside Derek Newark; and in A Study in Terror (both 1965) as Home Secretary Henry Matthews.
He also participated in a 30-minute documentary titled Two in a Tiger.  This film follows his training as he learns to fly a De Havilland Tiger Moth.
In 1970 he provided the voice-over for an edition of the BBC documentary series Chronicle: "The Great Iron Ship", about the salvage and return from the Falkland Islands of the Isambard Kingdom Brunel ship SS Great Britain.
His penultimate role was in the film version of the BBC sitcom That's Your Funeral (1972) and his final appearance was in the 18th-century-set comedy-drama Mistress Pamela which was not released until after his death.
Foster died at 3 Holly Hill, Hampstead, NW3, in January 1973. His early death was found to be the result of suicide by hanging. He left a widow, the actress Eileen Kennally (who appeared in In Sickness and in Health); they had married in 1952 and had two sons. Foster's estate was valued for probate at £36,535, equivalent to £558,087 in 2023.
