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.
