by Augustin Bernard, Napoléon Lacroix
About the author
Born in 1855 and died in 1910, Napoléon Lacroix is listed by the Bibliothèque nationale de France as a French author. The clearest surviving records tie him closely to colonial Algeria, where he served in the administration as well as in the military.
Sources describing his career identify him as an honorary infantry battalion commander and as head of the Service des affaires indigènes at the Governor-General of Algeria. He is known in particular as the co-author, with Augustin Bernard, of La pénétration saharienne (1830-1906), published in Algiers in 1906.
That book helps explain why his writing still surfaces today: it offers a period view of French expansion in the Sahara, combining administrative knowledge, military perspective, and historical narrative. Beyond those core facts, detailed biographical information appears limited in the sources I could confirm.
