Mark Haddon was born in Northampton in 1962. He graduated from Oxford University in 1981, returning later to study for an M.Sc. in English Literature at Edinburgh University. He then undertook a variety of jobs, including work with children and adults with mental and physical disabilities. He also worked as an illustrator for magazines and a cartoonist for New Statesman, The Spectator, Private Eye, the Sunday Telegraph and The Guardian (for which he co-wrote a cartoon strip).
His first book for children, Gilbert's Gobstopper, appeared in 1987 and was followed by many other books and picture books for children, many of which he also illustrated. These include the 'Agent Z' series and the 'Baby Dinosaurs' series. From 1996 he also worked on television projects, and created and wrote several episodes for Microsoap, winning two BAFTAs and a Royal Television Society Award for this work.
In 2003 his novel, The Curious Incident of the Dog in the Night-Time, was published and has been hugely successful. It is the first book to have been published simultaneously in two imprints - one for children and one for adults. It has won a string of prestigious awards, including the 2003 Whitbread Book of the Year. His second novel, A Spot of Bother, was published in 2006 and shortlisted for the 2006 Costa Novel Award.
His first book of poetry, The Talking Horse and the Sad Girl and the Village Under the Sea, was published in 2005.
His latest books are a new novel, Boom! (2009) and a picture book, Walking on The Moon (2009).
