This article deals with the goals, practices, and transformations of collaborative research that emerged between and within bureaucratic and bourgeois models of science organization in the late Habsburg monarchy. It offers novel insights into the political, social, and epistemic dimensions of public engagement in research, and evaluates the frameworks, profit expectations, and challenges involved. As will be exemplified by joint undertakings in the High Alps, the “Orient,” and the Adriatic Sea, private-public partnerships in the form of scientific societies or institutional alliances assumed vital functions. Their stakeholders volunteered for large-scale research projects, coordinated and funded infrastructure such as field stations, research vessels, or collecting expeditions, and became driving forces in establishing new forms of intra-imperial and cross-border collaboration. As such, scientific societies are useful indicators for understanding science-related developments and for illuminating the tensions between imperialism, (inter)national aspirations, and civil-society building. Based on sources from the archives of the k.k. Meteorological Society, the Natural Scientific Oriental Society, and the Adriatic Society, this article will analyze scientific collaboration as a purposeful and power-related interaction process, oriented toward mutual benefits, that took place on three levels: between state-owned research facilities and private societies, between bureaucrats and bourgeois, and between scientists and “non-professionals.”
