Gaston Leroux (1868–1927) was a French journalist and court reporter before becoming a novelist. He covered criminal trials and sensational cases for major Paris newspapers, developing the instinct for documentation and dramatic pacing that shapes Phantom's journalistic frame. He wrote the novel in 1909-10 while the Palais Garnier — the opera house that serves as the novel's setting — was still the dominant cultural monument of Paris. Leroux conducted genuine research into the opera house, including its underground construction, and may have heard local legends about a man living in the cellars during the building's construction. The novel was initially serialized and then published to modest response; it became internationally famous through the 1925 silent film adaptation and later through Andrew Lloyd Webber's 1986 musical.

How the Era Shapes the Book

The Belle Époque was a period of enormous public spectacle and private anxiety — the glittering surface of European civilization simultaneously at its height and approaching its collapse in WWI. The Palais Garnier was its architectural emblem: all gold and marble above, all underground passages and mechanical systems below. Leroux's Gothic is specifically a Belle Époque Gothic: the monster is not a vampire from Eastern Europe but a French engineer, hiding not in a castle but in the infrastructure of a cultural institution. The horror is domestic, technical, and intimate.
