Le Dépôt général de la Guerre, chargé de fournir les cartes nécessaires aux armées, connut sous la Révolution une période d'instabilité. La politique ambitieuse de Calon, son directeur, se heurta à la rivalité d'autres institutions civiles et militaires. Une période de lente reconstruction s'ouvrit avec le pouvoir napoléonien qui posa les bases rationnelles de la cartographie moderne et mit fin à la précarité du statut des ingénieurs-géographes en militarisant leur corps. La création simultanée d'une Ecole d'application des ingénieurs-geographes assura dès (...) lors une formation cohérente et de haut niveau dans le sillage de l'Ecole polytechnique, remplaçant les cours créés au Dépôt par Calon qui avaient jusqu'alors conservé jalousement leur autonomie. Puissant, qui y fut pendant vingt ans le professeur de mathématiques, introduisit l'analyse à l'école. Son oeuvre fut consacrée par son élection à l'Académie des Sciences au siège de Laplace et par le succès de la nouvelle carte de France au 1/80 000. L'ensemble de la période est marqué par la prise de conscience des enjeux de la géographie, par la mise en place des outils scientifiques de la cartographie et par la professionnalisation des ingénieurs-géographes. Disposant de son école et de son journal au même titre que les grands corps techniques, le Dépôt général de la Guerre était alors, entre l'Ecole polytechnique et le Bureau des Longitudes, une institution savante reconnue par la communauté scientifique.The Dépôt général de la Guerre, in charge of military mapping, experienced a period of change during the French Revolution. The new trends which then arose are explored here. Firstly, its director Calon failed in setting up an ambitious policy for geography, which challenged other civilian or military institutions. The courses he instituted to train surveyors collapsed. A time of slow reconstruction followed under Napoleonic rule, when the rational bases of modern cartography were laid as the ingénieurs-géographes were given a firm military status. In fact, a training school was created within the Ecole Polytechnique system, instead of the obsolete independent training courses. Henceforth, a high-level, coherent education was provided. Puissant, who was to teach mathematics there for twenty years, introduced analysis into the new school. His geodesic work was honoured by his succeeding Laplace at the Académie des Sciences, and by the success of the new 1:80 000 map of France. Eventually, the awareness of the importance of geography, the establishment of modern scientific tools in cartography, and the professionalization of the ingénieurs-géographes mark the whole period. The Dépôt général de la Guerre had its own school and journal, like any other corps of the technical Establishment. Thus it was a true scientific institution between the Ecole Polytechnique and the Bureau des Longitudes, and the scientific community recognized it as such. (shrink)

French science of the period between 1793 and 1830 is now a major focus of study. The large body of work produced since the nineteenth century, particularly in the field of institutional history, has provided the background for important attempts in the last ten or fifteen years to apply tools of sociological analysis to this field of enquiry. Particularly important have been theories of professionalization and institutionalization. It is the purpose of this paper to examine the consequences of the use (...) of such models in relation to this specific historical context. In particular, I shall suggest that such questions as the importance of institutions in the conduct of science, and the extent to which science became a profession or remained a vocation, may be better understood once the world of French science has been situated in a wider political and intellectual context. An article, however, can do no more than suggest new perspectives, and must leave to more extended treatments the work of amplification and correction. Briefly, however, this paper will argue for a view of science at this period as locked in a conflict between the ambiguous demands of the political world on the one hand, and on the other pressures on individuals and groups within the vocation of science to conform to an ideology which viewed science as completelynon-political.

An account is given of the emergence of the concept of work as a basic component of mechanics. It was largely an achievement of engineer savants in France during the Bourbon Restoration , with Navier, Coriolis and Poncelet playing the major roles. Some aspects of the eighteenth-century prehistory are described, and also concurrent developments in French engineering. The principal problem areas were friction, hydraulics, machine performance and ergonomics, and especially in the last context the developments became involved with social and (...) even philosophical movements in the 1820s. Education played an important role throughout; several of the principal sources are textbooks. (shrink)

Political difficulties and adverse working conditions during the Restoration period obliged many French scientists and technologists to seek employment elsewhere. Lamé and Clapeyron made the most of their years of exile, and in this paper their contribution to the development of Russian engineering is studied, together with their work for the future of French industry. Their scientific and technological research is also considered. Archival sources throw new light on the significance of their ten years in Russia.
