author
b. 1882
Little verifiable information appears to survive about this early 20th-century writer, which gives the name an air of mystery. The available records suggest a birth year of 1882, but biographical details are scarce.

by John Victor Lacroix
Research during this session turned up only limited, fragmentary information for John Victor Lacroix, and I could not confidently confirm more than the reported birth year of 1882.
Because the record is so thin, it would be risky to add details about nationality, career, major works, or later life without stronger evidence. If you have a title, publication date, or alternate form of the name, that would likely make it possible to build a fuller and more reliable author profile.
For now, the safest summary is that John Victor Lacroix appears to be an obscure author from the late 19th or early 20th century whose surviving public biography is very limited.
