Abstract
This paper looks at a genre of meetings that, while neither purely ‘scientific’ nor ‘diplomatic’, drew on elements from both professional spheres and gained prominence in the interwar decades and during the Second World War. It proposes to make sense of ‘technical conferences’ as a phenomenon that was made by and through scientific experts and politicians championing the organizing power of rationality, science and liberal internationalism. Against the background of swelling ranks of state-employed scientists, this paper documents the emergence of technical conferences as the forums where they got down to work. To make this case the paper traces the influence of a new way of thinking about the function and organization of conferences, originating in the time around the First World War, on one international organization in particular: the United Nations Relief and Rehabilitation Administration (UNRRA), as a new hub of scientists and technicians.
