Guy Louis Busson du Maurier DSO (18 May 1865, London, England – 9 March 1915, Kemmel, Flanders, Belgium) was an English army officer and playwright.

[7][8][9] The play tells the story of the Brown family caught up in the invasion of Britain by a foreign power identified as "Nearland"[10] but widely assumed to represent Germany.

[11] When the play was staged in Germany, it caused an outrage, as the German press saw clear references to their homeland.

In 1940 it was made into a propaganda film, more pointedly titled "Mad Men of Europe".

[12] At the death of his sister Sylvia, and as requested in her will, he became co-guardian to the Llewelyn Davies boys who inspired Peter Pan.
