Michael Sage

Michel Sage was a French author who lived from 1863 to 1931 and wrote in French. Records from the Bibliothèque nationale de France list him as the author of 13 works, with subjects connected to philosophy, religion, esotericism, and parapsychology.

He is best known in English for Mrs. Piper & the Society for Psychical Research, a 1904 translation by Noralie Robertson of his French work on the American medium Leonora Piper. The book presents psychical research as a meeting point between scientific investigation and spiritual questions, and it helped bring Sage's ideas to English-speaking readers.

Available source material suggests he wrote around a dozen books and also translated other spiritualist and psychical works, including writings by William Crookes and Edward T. Bennett. Among the titles associated with him are Madame Piper (1902), La zone frontière entre l'autre monde et celui-ci (1903), Le sommeil naturel et l'hypnose (1904), L'Ascension cosmique de l'homme, avec preuves (1930), and Le Spiritisme, problème scientifique (1931).
