William Frédéric Edwards was a French physiologist, of Jamaican background, who was also a pioneer anthropologist. He has been called "the father ofethnology in France".
Edwards began independent research in 1815–6, working on manganese oxide compounds with Pierre Chevillot. At the same time he began investigations on asphyxia in animals. Edwards was a vitalist who studied the effect of physical forces on processes in living organisms. His work led to the book De l'influence des agens physiques sur la vie . Edwards was following a direction in Lavoisier's research on "animal chemistry", and addressing questions raised in Magendie's journal. He carried out experimental work at the Collège de France.
Racial theories
Edwards was influenced by Amédée Thierry, to whom he addressed his 1829 essay Des caractères physiologiques des races humaines considérés dans leurs rapports avec l'histoire. Thierry had studied the backgrounds of the Gauls and Franks of the Late Antique period in France. Edwards took up a theory of "permanence of types", influenced also by René Primevère Lesson. As related by Edwards, he had been convinced of such a permanence since the early 1820s, when on a visit to London he was discussing the works of James Cowles Prichard with Hodgkin and Robert Knox. Knox convinced him, with the help of an Ancient Egyptian tomb exhibited by Giovanni Battista Belzoni, that Egyptian and other ethnic "types" persisted from antiquity. As Edwards made clear, his notion of "type" was flexible; and racial types became fundamental to 19th century debate on ethnology. He followed on from the studies of Johann Kaspar Lavater and Franz Joseph Gall in physiognomy, and pioneered the concept of race as determined by the shape of the face and head. He supplemented his physiological work with a study of the Celtic languages. Stendhal took his ideas on race from Edwards, who in fact established the concept of ethnologie in France. Another personal contact among writers was Jules Michelet: Edwards became his physician, and Michelet took ideas about "persistence of races" from Edwards and Thierry. This theorising applied very much to Europeans and particularly French people, and Edwards believed his own observations confirmed it. Edwards has been called the first anthropologist to discuss race. One of his concerns was justification of French nationalism. Edwards came to theorise broadly about human diversity, influenced by polygenism, and argued in favour of fixed types and characters attached to populations. He undermined the environmentalist monogenism of Prichard, in which climate had affected human populations after a single creation: he made a point of discounting the influence of climate on animal physiology in general. A remark he made about cross-bred animal populations, to the effect that one type comes to predominate, was quoted by Charles Darwin in The Variation of Animals and Plants under Domestication.
Edwards followed up his work correlating physiological characteristics with races, and other interests, by the foundation in 1839 of the Société Ethnologique de Paris, with a broader programme including also languages and traditions; its goal was to define human groups and identify their origins. The foundation of the Ethnological Society of New York and Ethnological Society of London followed within a few years. When Paul Broca founded the Société d'Anthropologie de Paris in 1859, he drew on the definition Edwards had given of ethnology.
