L’astronomie française à la Belle Époque. Professionnalisation d’une activité scientifique

This article describes the way French astronomy developed in the Belle Époque (ca. 1880-1914). It identifies and accounts for the specificities of a scientific practice, which, up until now, has been misrepresented in the history of science. We show how the practice of astronomy was rationalized by rigid procedures and integrated by a scientific-bureaucratic regime of activity. Established in state observatories (for example, the Paris Observatory), this regime defined astronomy as a professional activity practiced by a group of “workers” of the sky. Finally, the analysis of the regime enables us to shed a light on the process by which the cognitive content of the discipline of astronomy, the institutional framework constituted by the state observatories, and the group of professional astronomers all interacted and were indeed co-constructed.
