Mark Hall, who created much-loved British children’s animations including “Danger Mouse” and “Jamie and His Magic Torch,” died late Thursday night or early Friday morning in Manchester after a short illness. He was 75.

Hall worked closely with his college friend Brian Cosgrove. The two met at Manchester’s Regional College of Art in the 1950s and worked as graphic designers for the television channel Granada TV in the 1960s. They formed their own animation company, Cosgrove Hall Prods., in 1976 and went on to create a series of magical, often surreal cartoons.

Their best known creation was “Danger Mouse” — whose lead character, a cartoon secret agent mouse, first appeared on television in the 1980s with his sidekick hamster Penfold. The show attracted 19 million viewers at its peak.

They also created “Jamie and His Magic Torch” cartoons about a boy whose torch takes him to fantasy lands after bedtime. They also produced an animated version of Kenneth Grahame’s book “Wind in the Willows,” about riverside animals including Rat, Mole and Toad of Toad Hall.

Hall and Cosgrove retired in 2000 but had recently reformed their animation company under the name Cosgrove Hall Fitzpatrick Entertainment and had planned to produce new animation.

Hall’s son Simon will continue his father’s work. He is also survived by his wife, Margaret Routledge, whom he married in 1961, and a daughter, Rachel.
