La naissance de la spectrométrie : L'actinomètre électrochimique d’Edmond Becquerel

Abstract : The invention of photography has raised as a field of technology, but the scientific community was very quickly interested in it. First, used in his initial function, the picture achievement, its procedures are little by little adapted to the needs of research. We study, in this article, this transfer of methods, from the community of the technicians towards the scientific community, while analyzing the construction by Edmond Becquerel of a device, the electrochemical actinometer. This one, using the principles of photography allows studying the light through its effects on the matter. We equally analyze the influence of Edmond Becquerel’s double competence (1820-1891), as a scientist and as a photographer, in the success of this transfer that will drive him to the invention of what we can consider as the first spectrometer.
