Baraduc, Hyppolite (1850–1902)
Noted nineteenth-century French psychical researcher who
made interesting experiments in ‘‘thought photography’’ and
in 1895 addressed a communication on the subject to the
French Academy of Medicine. By photographic means he also
claimed to have proved that something misty and vaporous
leaves the human body at the moment of death. His contribution
to the study of vital emanation is significant. He constructed
an instrument, called Baraduc’s biometer, that indicated the
action of a nervous force and unknown vibrations outside the
human body. His experiments are described in his books The
Human Soul (1913), Iconographie de la Force Vitale Cosmique Od
(1896), Méthode de Radiographie Humaine (1897), Note Sommaire
sur la Décondensation Cérébrale (1901), Photographie des Etats Hypervibratoires
de la Vitalité Humaine (1897), Les Vibrations de la
Vitalité Humaine (1904), and La Force Vitale, Notre Corps Vital,
Fulidique, une Formule Barometrique (1905). (See also Sthenometer)
