Douglas John Cardew Robinson (14 August 1917 – 28 December 1992) was a British comic whose career was rooted in the music hall and Gang Shows.

Born in Goodmayes, Essex, Robinson was educated at Harrow County School for Boys. He enjoyed acting in school productions and loved the books of Frank Richards, featuring Billy Bunter of Greyfriars and the weekly magazine The Gem with the adventures of Ralph Reckness Cardew of St Jim's. In the early 1930s, while at Harrow County School, he wrote for the school magazine, The Gaytonian, using the pseudonym Hotbreaks.

On leaving school, Robinson took a job with a local newspaper, but it folded and he then joined Joe Boganny's touring Crazy College Boys, which opened at the Lyric Theatre, Hammersmith, London. However, Robinson knew that he required a more traditional training, and went into repertory theatre where one of his roles was as the monster in an adaptation of Frankenstein. It was while serving in the RAF during the Second World War that he created his 'Cardew the Cad of the School' character. Promoted to flight-sergeant and put in charge of the show, Robinson toured France, Belgium and the Netherlands.

After the war, he appeared with the commercial production of the Gang Show in variety theatres. Robinson began working in variety; he also played the Cad character on radio and stage. Later he played the character in a film, Fun at St. Fanny's. 'Cardew the Cad' became a cartoon strip in Radio Fun, a children's comic of the period.

Robinson had appeared in films as early as 1938, starting in a short in the series Ghost Tales Retold and following it ten years later with A Piece of Cake starring Cyril Fletcher. Robinson successfully made the transition from variety and radio into TV and films. In the latter, he nearly always played small but memorable cameo parts; thus, an early theatrical review mentioned "Mr Cardew Robinson, who seems to specialise in grotesques". Unusually, in the 1956 film Fun at St Fanny's he had one of the main roles, playing himself and received second to top billing.

One of his last appearances on television was in an episode of Last of the Summer Wine, in which Robinson, by then in his 70s, played a hen-pecked husband led astray by Compo and Clegg. He also appeared as a Second World War veteran turned priest in an episode of Hancock's Half Hour. When Hancock was holding a reunion of his old Army friends, Robinson was the only one who appeared not to have become staid and boring, but when he took off his scarf, it was seen that he had become a vicar.

In the production of Camelot in London in 1964, Robinson played King Pellenore. The show apparently ran for 650 performances, although it was not well received by the critics. The same year, Robinson's television work included the series Fire Crackers, featuring the day-to-day challenges and mishaps of the Cropper's End Fire Brigade.

In 1967, he appeared in The Avengers episode entitled "The 50,000 Pound Breakfast" as a Minister.
