Comprendre la structure moléculaire du vivant au début du XXe siècle : Une biographie scientifique d'Henri Devaux (1862-1956)

Abstract : Trained by Gaston Bonnier (1853-1922) in Paris at the end of the 1880s, Henri Devaux (1862-1956) was numbered among the most promising botanists of his generation due to his work on gaseous exchanges of aquatic plants. Between 1906 and 1932, he was professor of plant physiology at the Faculty of sciences of Bordeaux. Even though it was not his primary field of study, he slowly developed an interest in the physico-chemistry of thin films (or layers) and became one of the most prominent figures of the French school that emerged on this topic in the 1910s. Throughout the first third of the 20th century, his works on surface were considered as a reference in this field, also in the United States, and opened him the doors of the Académie des sciences. Thin layers were also for him a way to understand the structure and functions of cellular membranes and, consequently, of the life on the molecular scale. Having worked on almost 10 000 pages of his unexplored laboratory notebooks, we have reconstructed the salient points of his investigative pathway in this field.Rooted in a protestant faith, Devaux also tried to show with science popularization writings that scientific knowledge and the Bible are in harmony. He defended a fixist creationist vision of the world. Devaux regularly linked science and religion in his laboratory notebooks and even claimed his faith in an article published in the Journal de physique.
