Jimmy Nervo (born James Henry Holloway; 2 January 1897 – 5 December 1975) and Teddy Knox (born Albert Edward Cromwell Knox; 12 July 1896 – 1 December 1974) were English comedians who formed a double act and were part of the original Crazy Gang comedy group.
They performed as acrobats and knockabout comedians in revues for Albert de Courville, and in 1923 presented "Fantastic Frolics" on an all-British bill at the Palace Theatre on Broadway in New York.
In turn, this led to the formation of the "Crazy Gang", with Caryll and Mundy replaced by Flanagan and Allen.
Although Flanagan and Allen are in hindsight the best-remembered of the Crazy Gang members, it was Nervo and Knox who "always had the number one dressing room".
Jimmy "Nervo" Holloway married Minnie Schimmler in 1939; she had performed as Minna Scott with the D'Oyly Carte Opera Company.
