What is the title of the 1904 stage play that introduced Peter Pan to audiences?

The 1904 stage play was titled Peter Pan; or, the Boy Who Wouldn’t Grow Up.

J. M. Barrie’s play premiered in London in December 1904. Its subtitle identifies the central idea of Peter’s character: he refuses the ordinary process of growing older and accepting adult responsibilities.

The stage play developed material from Barrie’s earlier writing, including Peter Pan in The Little White Bird and later related stories. It established features that became standard in later adaptations, including Neverland, Wendy Darling, Tinker Bell, Captain Hook, and the Lost Boys.

The title is frequently shortened to Peter Pan, especially in general conversation. The complete title matters because later publications and adaptations use several related names, including Peter and Wendy for Barrie’s 1911 novel. Those titles refer to connected but distinct works.
