The subject “Science and Technology in the First World War” has so far been treated from the perspective on inventions and the development of new weapons, and often the focus has been on the topic of chemical warfare at the expense of other important dimensions. The approach of this Archival Research Guide, by contrast, comes from the social sciences and focuses on the establishment of relevant scientific, military and governmental bodies and on the personal networks established during the war. By examining these institutions and networks country by country, comparisons between them can be drawn, enabling further research with regard to the sociology of institutions. By pointing to the connections and channels of exchange between the nations and institutions under consideration, this approach opens up a transnational perspective and supports the paradoxal insight that transnational ties can dissolve national obstacles while simultaneously strengthening the nation-states themselves. On the individual level, the ARG takes the role of intellectuals into account, for whom scientific objectivity / neutrality and patriotic commitment seemed to have been no contradiction. It is remarkable that the First World War led to the establishment of several institutions aiming at funding science through the state, most notably in the case of France (CNRS), the U.S. (NACA/NASA) and Russia (KEPS).
