Whilst best known as a Nobel laureate physiologist, Charles Robert Richet was also a pioneer of scientific psychology. Starting in 1875 Richet had a leading role in the habilitation of hypnosis, in the institutionalization of psychology in France, and in the introduction of methodological innovations. Authoring several psychology books, Richet's works contributed to the recognition of the scientific nature of the discipline. This role is often underplayed by some historians and psychology textbooks in favor of his later position as a proponent of the controversial discipline he christened metapsychics in 1905, which today lies within the province of parapsychology. In this article, we show how his psychological approach guided by physiology, or physiological psychology, facilitated the reception of psychology. We hypothesize a strong continuity between his physiological psychology and his metapsychics, as he himself considered metapsychics as an advanced branch of physiology, and thus also an outpost of psychology.
| A MULTIFACETED MANThe science of life merges with the science of thought, and I foresee for the future magnificent horizons (Richet, 1933, p. 156).The figure of Charles Robert Richet (1850-1935) has already been the subject of several works that have focused on one or another of his multiple facets 1 . Psychology was only one chapter of his work. During the commemoration of the centenary for his Nobel Prize at the French Academy of Medicine (Van Wijland, 2015), a discussion of his physiological works included: temperature regulation in animals, gastric juice and digestion, lactic fermentation, serum therapy, botanic physiology, and his discovery of anaphylaxis for which he was awarded the Physiology or Medicine Nobel Prize in 1913. Other speakers analyzed his efforts to improve the international communication of scientific works, especially through the Revue Scientifique which he edited from 1878 to 1902; his patriotic pacifism; his adhesion to eugenics (see later discussion on "The internal dissymmetry of an 'amateur'"); his pioneering work in aerospace, including monoplanes with Tatin and the gyroplane with Breguet; his varied literary work; and finally his role in the establishment of "métapsychique" (metapsychics) (Richet, 1905b).Variously perceived as a Jack of all trades or as a genius able to span various disciplines (Estingoy, 2003), psychology historians Carroy, Ohayon, and Plas (2006, pp. 56, 57) depict Richet as the most striking case of "duplicity," since he had both a scientific career and a literary/dramatic one under the pseudonym of Charles Epheyre, sharing his dreams and thoughts on science, society, and the paranormal. We might go further and say it was more a striking case of multiplicity, for Richet was the perfect example of a Renaissance man.Passionate about science, Richet devoted his life to research where his governing principle was "never sacrifice anything to laboratory work" and in 46 years he accumulated some 50,000 h of experimental research (Richet, 1927b, p. 63).
