author
1855–1910
A French military officer and colonial administrator, he wrote about North Africa and the Sahara from direct experience inside the French administration in Algeria. His surviving works offer a revealing window into how expansion, control, and geography were described at the start of the 20th century.

by Augustin Bernard, Napoléon Lacroix
Born in 1855 and died in 1910, Napoléon Lacroix is identified in major French library records as a writer as well as a military figure. Catalog and authority records describe him as an honorary infantry battalion commander and as head of the Service des affaires indigènes at the Government-General of Algeria.
He is best known today for works connected to French Algeria and the Sahara, including books written with Augustin Bernard such as La pénétration saharienne (1830-1906) and L'Évolution du nomadisme en Algérie. Those books reflect his administrative background and focus on the history, movement, and control of Saharan regions under French rule.
Because the available sources found here are mainly library and archival records rather than full biographical studies, only a limited personal portrait emerges. Even so, they show him as a late-19th- and early-20th-century author whose writing is closely tied to colonial policy, geography, and the French presence in Algeria.
