François-Napoléon-Marie Moigno

He received his early education at the Jesuit college at Sainte-Anne-d'Auray and entered the novitiate of the Society of Jesus on 2 September 1822.

In 1836 he was appointed professor of mathematics at the College of Sainte-Geneviève, Rue des Postes, in Paris.

He wrote numerous articles for the press; he was engaged on one of his best known works, "Leçons de calcul différentiel et de calcul intégral", based chiefly on Cauchy's methods, and had already published the first volume, when he left the Jesuit Order in 1843.

Shortly afterwards he undertook a tour of Europe, contributing numerous letters to the journal "L'Epoque".

He also translated numerous English and Italian memoirs on science into French, and edited the "Actualités scientifiques".
