N.-J. Carpentier

Nicolas-Joseph Carpentier was a 19th-century French-language author, listed by Project Gutenberg as Carpentier, N.-J. (Nicolas-Joseph). The work most clearly linked to him is Dictionnaire du bon langage, a reference book on difficulties in French, pronunciation, and improper or regional usages.

A bibliographic note on the French Wikisource discussion page identifies him as Carpentier, Nicolas Joseph, 1824 and gives the 1860 Liège publication details for Dictionnaire du bon langage. The BnF catalogue also attributes that book to l'abbé N. J. Carpentier, which suggests he was a clergyman as well as a language teacher or guide for readers.

Very little biographical information beyond those catalog records was readily confirmed, so the safest picture is a modest one: Carpentier appears to have been a 19th-century abbé remembered chiefly for a useful handbook on correct French usage.
