author
b. 1859
Best known for a lively French book on Queen Victoria, this little-documented writer seems to have worked as a popular biographer or historical storyteller rather than a major literary celebrity.
J.-H. Aubry is an elusive figure today, and the clearest detail I could confirm is the work most closely associated with the name: La reine Victoria intime, a French book available through Project Gutenberg. The book presents Queen Victoria's early life and rise to the throne in an accessible, narrative style, suggesting an author interested in bringing well-known history to a broad reading audience.
Beyond that title, reliable biographical information appears scarce in the sources I found. Because of that, it is safest to describe Aubry as a late-19th- or early-20th-century French-language writer whose surviving reputation rests mainly on historical and biographical writing, especially about Queen Victoria.
I could not confirm a fuller personal biography, major career milestones, or a trustworthy portrait for this author from the sources available here, so those details are best left open rather than guessed.
