Frederick Piper (23 September 1902 – 22 September 1979) was an English actor who appeared in over 80 films and many television productions in a career spanning over 40 years. Never a leading player, Piper was usually cast in minor, sometimes uncredited, parts although he also appeared in some more substantial supporting roles. Piper never aspired to star-status, but became a recognisable face on the British screen through the sheer volume of films in which he appeared. His credits include a number of films which are considered classics of British cinema, among them five 1930s Alfred Hitchcock films; he also appeared in many Ealing Studios productions, including some of the celebrated Ealing Comedies.
