Leon Denis
1846-1927

          APOSTLE OF French spiritism on whom the mantle of Allan Kardec fell. Indeed, he claimed to have been directly inspired by the spirit of Kardec in his activity as a tireless propagandist, teacher and author of important and popular books, also by a spirit which called himself Jerome of Prague, communicated through typtology since 1892 and addressed him as "my son." Between his first book d'Apres la Mort, which founded Leon Denis' popularity, and his last, Genie Celtique, et le Monde Invisible, written under the influence of Allan Kardec and posthumously published, the following works left his pen: Le Probleme de l'Etre et de la Destinie, Christianisme et spiritisme, Dans l'Invisible (Spiritisme et Mediumnite), Monde Invisible et la Guerre, Jeanne d'Arc Medium, L'Au-dela et la Survivance de l'Etre, La Grande Enigme.

The life and work of Leon Denis forms the subject of two books: Gaston Luce: Leon Denis l'apotre du spiritisme, sa vie, son oeuvre; Claire Baumard: Leon Denis intime.
