Peter Pan; or, the Boy Who Wouldn't Grow Up or Peter and Wendy is J. M. Barrie's most famous work, in the form of a 1904 play and a 1911 novel. Both versions tell the story of Peter Pan, a mischievous little boy who can fly, and his adventures on the island of Neverland with Wendy Darling and her brothers, the fairy Tinker Bell, the Lost Boys, and the pirate Captain Hook. The play and novel were inspired by Barrie's friendship with the Llewelyn Davies family. Barrie continued to revise the play for years after its debut until publication of the play script in 1928.Barrie created Peter Pan in stories he told to the sons of his friend Sylvia Llewelyn Davies, with whom he had forged a special relationship. Mrs. Llewelyn Davies's death from cancer came within a few years after the death of her husband. Barrie was named as co-guardian of the boys and unofficially adopted them.The character's name comes from two sources: Peter Llewelyn Davies, one of the boys, and Pan, the mischievous Greek god of the woodlands. Andrew Birkin has suggested that the inspiration for the character was Barrie's elder brother David, whose death in a skating accident at the age of fourteen deeply affected their mother.According to Birkin, the death was "a catastrophe beyond belief, and one from which she never fully recovered. If Margaret Ogilvy [Barrie's mother as the heroine of his 1896 novel of that title] drew a measure of comfort from the notion that David, in dying a boy, would remain a boy for ever, Barrie drew inspiration.
