Roald Dahl and Quentin BlakeRead about the other entries on the list.
Roald Dahl worked with other illustrators but it was only when he teamed up with Quentin Blake that the chemistry began to fizz. Quentin Blake is Britain's greatest living illustrator and has that special talent all the great illustrators have, of unobtrusive brilliance. He never grandstands, or overpowers the text, but quietly breathes a visual life in to it and, in so doing, makes it his own. Dahl appreciated that and held on to him for the rest of his career. A great collaboration!
