After National Service he did a postgraduate teaching diploma at the University of London, followed by life-classes at Chelsea Art School. He is known for his collaboration with writers such as Russell Hoban, Joan Aiken, Michael Rosen, and Roald Dahl, as well as creating much-loved characters of his own, including Mister Magnolia and Mrs Armitage. His books have won numerous prizes and awards, including the Whitbread Award, the Kate Greenaway Medal, the Emil/Kurt Maschler Award and the international Bologna Ragazzi Prize.
