Scientific textbooks are often said to deliver a stereotyped kind of knowledge, which conceals rather than reveals the real making of science. They may, however, alternatively be regarded as of peculiar interest for historians of science. An over-mechanical application of the Kuhnian concepts of ‘scientific revolution’ and ‘normal science’ can lead to the neglect of the internal dynamics of ‘normal science’. Scientific textbooks may provide a better understanding of the process of normalization in science.

Relations between J. A. C. Chaptal, pioneer of heavy chemical industry in France, and A. L. Lavoisier, reformer of chemical theory, are examined in the light of unpublished correspondence they exchanged in the period 1784–1790. The letters, together with Chaptal's early publications, allow a reconstruction of his conversion to Lavoisier's antiphlogistic chemistry. They also reveal a series of petitions that Chaptal made to Lavoisier, in the latter's official capacity as a director of the Régie des poudres et salpêtres, for relief (...) from the controlled price of saltpetre for his acid works in Languedoc. Finally, the relationship is explored as a window on the interplay between chemical theory and industrial practice during the period of the Industrial Revolution. (shrink)

In Éléments de l'art de la teinture, Claude-Louis Berthollet organized and described knowledge of a chemical craft in terms of contemporary chemical science. The resulting intellectual structure of his treatise established a programme and method for the subsequent improvement of dyeing. Berthollet's descriptive and hierarchical systematization of knowledge rendered problems intelligible and isolated them so that they could be attacked and solved by methodical experimentation. This double-edged processes of solving practical problems, first cognitively and then experimentally, provides a key to (...) understanding the way science has contributed to rapid and systematic technological change.

Historians of science have repeatedly, and justly, pointed to the discrepancy between theory and practice in the writings of Cuvier. This discrepancy is especially conspicious in his palaeontological works. No satisfactory analysis of the relation between theory and practice in Cuvier's palaeontology has appeared as yet. In this paper I shall point out the shortcomings of the interpretations of E. S. Russell, H. Daudin, W. Coleman, M. J. S. Rudwick and B. Balan. These authors either overrated or underestimated the role (...) Cuvier's anatomical rules played in his research. Next I shall argue that theory, as embodied in the anatomical rules, played an important role in Cuvier's study of fossil animals. However, the rules were not used as abstract principles of reconstruction. It is a persistent misconception that Cuvier's main concern in the Recherches sur les ossemens fossiles was the reconstruction of extinct animals. Most memoirs deal only with the identification, description and classification of fossil remains. It was mainly on this level that Cuvier—successfully—applied the anatomical rules. As an example of the use he made of the rules, Cuvier's study of the fossil mosasaur from Masstricht will be discussed. This example will also provide a clue to an alternative explanation of the discrepancy between theory and practice in the Recherches. I shall argue that Cuvier's theoretical claims must in part be qualified as examples of his great talent for image-building. (shrink)

In its attempt to achieve acknowledgement and support as a true science and academic discipline eighteenth-century chemistry experienced that the traditional distinction between theory and practice, respectively between science and art, was an incriminating heritage and did not longer conform to the way chemists saw themselves. In order to substitute the former, socially judging classification into theoretical science and practical art, J. G. Wallerius from Uppsala coined the term pure and applied chemistry in 1751. The idea behind this new conception (...) was that it ought to be chemistry's research aim and not the kind of work, be it manual or intellectual, which was to decide about its branches and their dignity. The change in orientation which took place during the eighteenth century, and which is symbolized by the new dichotomy “pure and applied”, led towards a revaluation of the utilitarian aspects of chemistry. Its historical roots reach back to a long and fruitful cooperation of, and interaction between chemistry and economy, which was reinforced by the Stahlian tradition in Germany and Scandinavia. Subsequently, it was its strong economic bias that helped chemistry to become institutionalized and accepted as an academic discipline distinct from the medico-pharmaceutical profession. The analysis of this change of attitudes, behaviour and institutional pattern suggests that, at least during the period of institutionalization of this particular discipline, social structures and the intrinsic scientific contents are so tightly interrelated, that any division into “internal”, cognitive developments and “external” conditions would be artificial, since they both constitute the scientific community as a context of argumentation and action.

Historians of science are less inclined now than they were a few years ago to regard chemistry as having sprung full-grown from the mind of Antoine-Laurent Lavoisier. Many of the contours of pre-Lavoisierian chemistry have recently been mapped, its Newtonian and Stahlian theoretical traditions have been delineated, and the degree of coherence enforced on the subject by its didactic role has been argued. In addition, the social prominence and cohesion achieved by chemists in various national contexts, such as France, Scotland (...) and Germany, have been investigated. Karl Hufbauer (arguing specifically from the case of Germany) and Christoph Meinel have proposed that the cultural climate of the European Enlightenment provided the language and the social settings in which chemistry could be detached from its previous role as a service-art for medicine, and presented as a science with diverse practical applications.
