Crafting Europe from CERN to Dubna: Physics as diplomacy in the foundation of the European Physical Society

The year 1968 is universally considered a watershed in history, as the world was experiencing an accelerated growth of anti-establishment protests that would have long-lasting impacts on the cultural, social, and political spheres of human life. On September 26, amid social and political unrest across the globe, 62 physicists gathered in Geneva to found the European Physical Society. Among these were the official representatives of the national physical societies of 18 countries in both Eastern and Western Europe, who signed the constitution in spite of the political divides of the Cold War. According to the main proponent of the society, Italian physicist Gilberto Bernardini, the success of the initiative was the realization of a dream: the institutional formation of a single community of European physicists, a representation of a culturally unified Europe that he described as a “single highly civilized nation.” The analysis of as yet unexplored archival materials of Bernardini and other protagonists in the establishment of the society has enabled an investigation of the historical development of science diplomacy in two interconnected ways: first, by elucidating how the actors involved, especially those in Western Europe, interpreted their role as diplomats amid particularly turbulent reconfigurations of international political relations; second, by interpreting the attempt to institutionalize transnational scientific networks with the establishment of a non-governmental organization as a tool to influence world political affairs. It will first be shown that the political ideal of a culturally unified Europe was deeply intertwined with the socio-professional interests of a specific community, mostly involved with CERN. I will argue that, in the process of establishing the society, the invasion of Czechoslovakia by Warsaw Pact armed forces led many of the Western physicists involved in this process to reframe the role of the European Physical Society as a tool to diffuse liberal-democratic values and to support political dissidents in Eastern Europe.
