This French cabinet maker began to form an interest in somnambulic phenomena around the year 1845, and began to record and investigate the trance utterances of various somnambules. In 1848 he published 'Arcanes de la vie Future Devoilees' and it relayed the many conditions under which discarnate spirits live. He published a second volume in 1849, in which he detailed séances held with Adele Maginot. This medium enabled sitters to communicate with loved ones who had passed away. Cagagnet is known for his good intentions, and his work remains some of the most viable of its nature.
