Simon James grew up in Bristol and Exeter. From an early age, he spent much of his time drawing and stapling stories into little books. After leaving school, Simon had many different jobs, while hoping to be a cartoonist. Later, he went to college to study graphic design and art history and returned to spending much of his time drawing and stapling stories into little books - and still does to this day.
Simon's first book, The Day Jake Vacuumed, was published in 1989. His other titles include: Dear Greenpeace, Sally and the Limpet, The Wild Woods, Baby Brains and The Birdwatchers. Leon and Bob won the Smarties Book prize Silver Award and was New York Times Best Illustrated Book of the Year.
