Jack Dunkley was born in London and educated at the Sir Hugh Middleton Secondary School. He started out working in the film industry, but eventually turned to cartooning in 1932. He was sports cartoonist for the Daily Mirror, and made a newspaper strip based on the radio comedy 'The Larks' from 1957. Radio scriptwriters Bill Killy and Arthur Lay were scriptwriters, followed by Robert St. John-Cooper and from 1963 on Brian Cook. 'The Larks' revolves around Sam Lark, a supermarkt employee married to his wife Sal. In 1961 they had a child, Stevie. Later episodes gave them a daughter named Susie. The family also took a pet, the cat Soso. 'The Larks' ran with equal success in French as 'Sam et Zette'.
Other strips by Dunkley were 'Patsy' and the gardening strip 'Mr Digwell'. Dunkley also contributed to the Radio Times, Daily Sketch, News Chronicle and Daily Express.
