Reine und angewandte Chemie Die Entstehung einer neuen Wissenschaftskonzeption in der Chemie der Aufklärung

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 (facts, theory and subject-matter) and “external” conditions (social context and stategies of institutionalization) would be artificial, since they both constitute the scientific community as a context of argumentation and action.     

„On employera les meilleurs Graveurs pour les Figures”︁. Zeichner und Stecher der Berliner Akademie der Wissenschaften, 1700–1806

“We will employ the best engravers for the figures” – Draughtsmen and Engravers of the Berlin Academy of Sciences, 1700–1809. – Although barely mentioned in accounts of its history of the Berlin Academy of Sciences, draughtsmen and engravers were, from the very inception, essential collaborators. Based on previously overlooked archival sources, this paper investigates the strategies that scientists used to select the most appropriate candidates during the first hundred years of the academy's existence. These included: (1) the engaging of artists already known to the scientists or those who had been recommendaded to them; (2) maintaining long‐term relationships with a number of artists, and later with their offspring (who had frequently been trained by their fathers); in 1768 this strategy culminated in the creation of a permanent position for one academic draughtsman; and (3) hiring draughtsmen who specialised in the subject matter in question, which entailed, for example, employing different people to carry out anatomical and botanical illustrations.     

Etappen auf dem Weg zu einer Geschichte der Pflanzenzüchtung. Überlegungen aus Anlaß eines Buches von Thomas Wieland

Thomas Wieland's book is the first survey on the history of scientific plant breeding in Germany from 1889 to 1945. There are two mainlines of analysis: (1) The transformation of an agricultural practise of peasants into an academic discipline of scientists and (2) the importance of political arguments for this process of scientification. Most of the time Wieland's methods to present his thesis are exemplary: either as biographies or as breeding project histories. So he can write about a great diversity of aspects; but from his point of view – the discipline history as applied science – he cannot show the great importance of economic forces controlling plant breeding. This short article will not diminish the high value of Wieland's book. My aim is only to outline some desiderata for a history of plant breeding which is not yet written.
