Christopher Wormell was born in Gainsborough, Lincolnshire in the house of his grandparents, though he lived most of his life in London.
Much of what he knows about art he has learned from his father, who taught painting at Hornsey College of Art.
In 1982, inspired by the book illustrations of Thomas Bewick, he took up wood engraving and, following a few commissions for book covers, managed to get himself an agent and break into the world of commercial illustration.
As well as illustrating books, he has since worked for newspapers, magazines and graphic designer, and has also worked on many advertising campaigns.
He began to write children's picture books in the 1990's, when he had children of his own; partly as a way of broadening the subject matter he could illustrate (up to that point no one had asked him to illustrate red dragons or ugly monsters or bears and walruses and elephants riding on little toy trains), but mainly because he just loved telling stories. He thinks writing and illustrating stories for children is the thing he enjoys the most.
