A Name on the Stage and the Page
In the 1800s, the name gained a new cultural dimension through Swedish soprano Christina Nilsson, born in 1843. Nilsson debuted as Violetta in La Traviata and performed at the Metropolitan Opera's inaugural production of Faust, building a career so celebrated that Gaston Leroux reportedly modeled his 1910 heroine, Christine Daaé, on her life story.
Leroux's novel The Phantom of the Opera cemented "Christine" in the literary imagination. Andrew Lloyd Webber's 1986 musical adaptation brought the character to Broadway and London's West End, where the show became the longest-running production in Broadway history.
