"Building the General Relativity and Gravitation Community During the Cold War" offers a comprehensive analysis of the development of general relativity in the context of the Cold War. This monograph highlights the challenges faced by prominent scientists as they sought to establish an institutional framework to promote the theory of relativity. The author, Roberto Lalli, examines the complex interactions between scientific and political factors and illustrates how these influenced the evolution of general relativity, despite the field having no military applications. The narrative explores why the theory of relativity led to a unique international scientific community and whether this was the result of specific actions by individual actors or the nature of the field itself. The book is aimed at historians of modern science, historians of international relations, as well as physicists and interested readers.
