Faith Jaques, born in 1923-1997, illustrated more than 100 books, including the first English edition of Roald Dahl's Charlie and the Chocolate Factory. She also designed postage stamps and greetings cards and was a regular contibutor to Radio Times. She also wrote children's books; her titles include Tilly's House and the Little Grey Rabbit's House pop-up books.
Here is an excerpt from her obituary in The Independent:
Faith Jaques was one of the outstanding illustrators responsible for the renaissance of British picture books during the last three decades. Her special gift was an ability to translate the emotional tone of a text into the strong visual atmosphere created by her pen-and-ink drawings. Coming to colour comparatively late she was equally adept here, illustrating texts she was now writing herself. Tilly's House (1979) - the story of a Dutch doll - was her first picture book as author and illustrator, and still remains one of her best. (Independent August 7th 1997)
