That science is fundamentally universal has been proclaimed innumerable times. But the precise geographical meaning of this universality has changed historically. This article examines conceptions of scientific internationalism from the Enlightenment to the Cold War, and their varying relations to cosmopolitanism, nationalism, socialism, and ‘the West’. These views are confronted with recent tendencies to cast science as a uniquely European product.

What Is Race? Evidence from Scientists is a picture book for schoolchildren published by UNESCO as part of its high-profile campaign on race. The 87-page, oblong, soft-cover booklet contains bold, semi-abstract, pared-down images accompanied by text, devised to make scientific concepts ‘more easily intelligible to the layman’. Produced by UNESCO’s Department of Mass Communication, the picture book represents the organization’s early-postwar confidence in the power of scientific knowledge as a social remedy and diplomatic tool. In keeping with a significant component (...) of the race campaign, What Is Race? presented genetics as the route to an enlightened, scientific, non-prejudiced understanding of race. This article seeks to explain the book’s management, aesthetics and framing in the context of postwar disciplinary and international politics. Viewing UNESCO’s race campaign as a high point for an internationalist ideology of mass education, this article also analyses the visual and literary arguments of What Is Race? and proposes that the enduring image of genetics as technical and neutral knowledge was in part shaped by UNESCO’s efforts to communicate scientific authority to an apparently ‘popular’ audience.

The political engagement of scientists is not necessarily left-wing, and even when it is, it can take widely varying forms. This is illustrated by the specific character of Dutch scientific activism in the 1930s and 40s, which took shape in a society where ‘pillarized’ social divisions were more important than horizontal class structure. This paper examines how, within this context, the Delft physicist Jan Burgers developed a version of scientific politics, built on a philosophy of value-laden science.
