Clive Dunn OBE (born January 9, 1920) is a retired British actor, singer and entertainer best known for his role as Lance-Corporal Jack Jones in the BBC sitcom, Dad's Army.
Born in London, a cousin of actress Gretchen Franklin, Dunn played small film roles from the 1930s onwards. After a break for service in World War II, in the course of which he spent four years in a prisoner-of-war camp, it was not until the 1960s that he finally broke into television comedy, making his name by appearing with Tony Hancock, Michael Bentine, Dora Bryan and Dick Emery, among others, before winning the role of Jones in Dad's Army in 1968.
From an early time his trademark character was that of a doddering old man. This first made an impression in the show "Bootsie and Snudge", a spinoff from "The Army Game". Dunn played the old dogsbody at a slightly seedy gentlemen's club where the characters Pvt. "Bootsie" Bisley (Alfie Bass) and Sgt. Claude Snudge (Bill Fraser) found work after leaving the Army.
