The aftermath of the Second World War represented a major turning point in the history of French and European physical sciences. The physicist's profession was profoundly restructured, and in this transition the role of internationalism changed tremendously. Transnational circulation became a major part of research training. This article examines the conditions of possibility for this transformation, by focusing on the case of the summer school for theoretical physics created in 1951 by the young Cécile Morette (1922-2017), just in front of Mont Blanc, at Les Houches. First I show that ultimately it was only thanks to extremely specific and intertwined social positions and dispositions, in terms of class and gender (derived from her socialization as an expected dame de la bourgeoisie), and through the interactions between such social attributes and a dramatic life event, that Morette managed to gather a network diverse, powerful and transnational enough to create this institution. Then, following the first years of this school, I show how it became an international model, paving the way to new articulations between the local, the national and the global scales, even beyond the Cold War oppositions.

Cécile Morette 和 Les Houches 理论物理暑期学校；或者，女童子军、1944 年卡昂爆炸案和求婚如何帮助重建法国物理学（1951-1972）

第二次世界大战的后果是法国和欧洲物理科学史上的一个重大转折点。物理学家的职业发生了深刻的重组，在这种转变中，国际主义的作用发生了巨大的变化。跨国流通成为研究培训的主要部分。本文以年轻的 Cécile Morette（1922-2017 年）于 1951 年在 Les Houches 的勃朗峰前创建的理论物理暑期学校为例，研究了这种转变的可能性条件。首先，我表明，最终这只是由于在阶级和性别方面（源自她作为预期的资产阶级贵妇的社会化）极其具体和交织的社会地位和性格，通过这种社会属性和戏剧性生活事件之间的相互作用，莫雷特设法聚集了一个足够多样化、强大和跨国的网络来创建这个机构。然后，在这所学校的最初几年之后，我展示了它如何成为国际模式，为地方、国家和全球范围之间的新衔接铺平了道路，甚至超越了冷战反对派。
