Peter Pan by JM Barrie

Barrie's most famous and enduring work, Peter Pan, or The Boy Who Wouldn't Grow Up, had its first stage performance on 27 December 1904. This play introduced audiences to the name Wendy, which was inspired by a young girl, Margaret Henley, who called Barrie 'Friendy', but could not pronounce her Rs very well and so it came out as 'Fwendy'. It has been performed innumerable times since then, was developed by Barrie into the 1911 novel Peter and Wendy, and has been adapted by others into feature films, musicals, and more.
