The papers in this volume represent the first attempt at a coherent analysis of the institutional structure of French science and technology in the nineteenth century. They treat both research and education and cover the main developments in the period from the establishment of the Napoleonic University in 1808 to the outbreak of the First World War. The papers reflect the intense interest in the social history of French science since the Revolution and convey a vivid impression of different modes of thought in a particularly active field of research. The contributions stress and develop more clearly than in any previous study, the theme of structural change in a complex interlocking network of institutions. Far from being an unresponsive monolith, France's system of scientific research and education proved capable of significant modification and expansion, especially in the later nineteenth century. To an extent that has not been fully recognised by historians, the French did respond to the changing demands of an industrialising economy and to the intellectual, economic and political challenge of the new Germany - a point that needs to be taken into account in discussions of the supposed decline of French science in the nineteenth century.
