Stacy Aumonier (31 March 1877 – 21 December 1928) was a British writer and stage performer, most highly regarded for his short stories. Between 1913 and 1928, he wrote more than 85 stories, 6 novels, a volume of character studies, and a volume of 15 essays. The Nobel Prize winner (and Forsyte Saga author) John Galsworthy described Aumonier as "one of the best short-story writers of all time" and predicted that, through the best of his stories, he would "outlive all the writers of his day."
