roger frontenac or reynaud-plense?

Bonjour

The Lyon’s public library organized a virtual exhibition Prophéties pour temps de crise : interpretations de Nostradamus au fil des siècles in 1997, on Nostradamus and his prophecies.
And, on this note about La Clef Secrète de Nostradamus , it seems like this book has two authors : Roger Frontenac and Charles Reynaud-Plense.


After a research on our library catalog, we can show you that La Clef Secrète de Nostradamus was written by Roger Frontenac. And Charles Reynaud-Plense was “only” the writer of the lexicon.

Roger Frontenac and Charles Reynaud-Plense are two different persons:
Roger Frontenac was a navy officer, in charge of military cyphers. After World War II, he studied the work of Nostradamus. He published his treatise about Nostradamus' letters and works, La clef secrète de Nostradamus (The Secret Key of Nostradamus). In the book, Frontenac professed his belief in Nostradamus as a true prophet, who made correct foretellings, and that the centuries (in French Les Propheties) contained true predictions about future events until the year 3797.

Charles Reynaud-Plense was the assistant curator of the Musée de l’Empéri, a museum about military history.
