This paper sketches how late seventeenth-century Dutch anatomists used printed publications to advertise their anatomical preparations, inventions and instructional technologies to an international clientele. It focuses on anatomists Frederik Ruysch and Lodewijk de Bils , inventors of two separate anatomical preparation methods for preserving cadavers and body parts in a lifelike state for decades or centuries. Ruysch's and de Bils's publications functioned as an ‘advertisement’ for their preparations. These printed volumes informed potential customers that anatomical preparations were aesthetically pleasing and (...) scientifically important but did not divulge the trade secrets of the method of production. Thanks to this strategy of non-disclosure and advertisement, de Bils and Ruysch could create a well-working monopoly market of anatomical preparations. The ‘advertising’ rhetorics of anatomical publications highlight the potential dangers of equating the growth of print culture with the development of an open system of knowledge exchange. (shrink)

This article reviews several strategies of technology transfer in early modern Central Europe and will focus especially on transfers between individuals: the transfer of know-how in the context of apprenticeship that became an institutionalized kind of professional education; and the transfer of technology by migration. The essay deals with different evaluations of the effects of technology transfer in the crafts production and will reflect recent discussions of the advantages and disadvantages of the tramping system. The intensive debate over the utility (...) of tramping began in the eighteenth century, especially in the contemporary scientific journals and as a question in academic prize competitions. The discussion stressed all the strategies of transfer. In special workshops – as in porcelain manufacturing – the protection of know-how was widespread. While some European states like England in the later eighteenth century tended towards a policy of secrecy, the German territories depended on the acquisition of new technologies, and therefore preferred a policy of openness in technological knowledge.

This paper considers inventors' rights as revealing shifts in the elaboration of public trust in inventions. The two main issues, the method of invention and the credit invested, are analysed both in terms of Diderot's writings and in the economic, social and political context of invention during the eighteenth century. In a pamphlet written in 1755, Histoire et secret de la peinture en cire, Diderot criticized the Count of Caylus's attempt to keep the invention of wax painting secret and to (...) enhance his fame thanks to this technical achievement. Diderot developed a conception of invention as an activity based upon methodical rediscoveries, imitations and translations. Although this could also concern artistic practice, imitation in art had a quite different meaning for Diderot. The main issue was the status of artists and inventors in society. Personal glory and private appropriation were denied to inventors, in contrast to artists. Secrecy, pride and exclusivity in invention were mean and ridiculous strategies. This was precisely what had been happening since the beginning of the eighteenth century, with the development of a market for inventions and exclusive titles, which also affected art. Diderot's narrative of invention as a daily, collective and historical process echoed the necessity of reassessing the value of invention by the criteria of public utility and shared evaluation.

Openness is one of the most important principles in scientifi c inquiry, but there are many good reasons for maintaining secrecy in research, ranging from the desire to protect priority, credit, and intellectual property, to the need to safeguard the privacy of research participants or minimize threats to national or international security. This article examines the clash between openness and secrecy in science in light of some recent developments in information technology, business, and politics, and makes some practical suggestions for (...) resolving confl icts between openness and secrecy.

Le but de cet article est d'interroger les transformations culturelles qui accompagnent la commercialisation des inventions, phénomène majeur de l'essor marchand et consumériste au XVIIIe siècle. Les stratégies commerciales des inventeurs sont fondées sur une médiatisation croissante, mêlant rhétoriques visuelles (démonstrations, spectacles, expositions) et recours à l'imprimé: annonces de presse, affiches, prospectus, modes d'emploi, livrets d'utilisation. L'information et le savoir techniques jouent un rôle clef dans la construction de marchés pour les inventions. Cette dimension a rarement été prise en compte (...) dans l'histoire de la consommation et dans l'histoire des techniques. Pourtant, la littérature d'usage, qui postule l'autonomie et la capacité participative de l'acheteur comme argument de vente, exprime la montée en puissance des savoirs d'action, opératoires, prescriptifs, où priment le verbe et le geste, l'intention et le projet. Si la technologie des Lumières se déploie dans les traités et les dictionnaires, elle se manifeste aussi dans cette littérature éphémère, pratique et commerciale, source d'appropriations. (shrink)
