Originairement installé à l'angle sud du quadrilatère de la cour des Ernests, rue d'Ulm, le laboratoire de physique de l'Ecole normale supérieure s'installe ici en 1940, pour prendre réellement son essor après la guerre, avec la nomination d'un nouveau directeur, Yves Rocard. Plus spacieux, les locaux permettent alors la venue d'un certain nombre de professeurs et de chercheurs, et une redéfinition de la politique de recherche à un très haut niveau des orientations novatrices se dessinent vers la géophysique, la physique des solides et en particulier les semiconducteurs, la radioastronomie et la physique des particules et des hautes énergies. Dès les années 1950, l'extension de ce laboratoire rend nécessaire son essaimage vers Orsay, Nançay, Meudon et d'autres centres. Par le développement de ses ressources et son ouverture sur l'extérieur, le laboratoire de l'Ecole normale supérieure a joué un rôle considérable dans le renouveau de la physique française.
Originally located in the southern corner of the Cour des Ernests quadrangle on Rue d'Ulm, the Physics Laboratory of the École Normale Supérieure moved here in 1940, truly taking off after the war with the appointment of a new director, Yves Rocard. The more spacious premises then allowed for the arrival of a number of professors and researchers, and a redefinition of the research policy at a very high level led to innovative directions being taken in geophysics, solid-state physics (particularly semiconductors), radio astronomy, and particle and high-energy physics. By the 1950s, the expansion of this laboratory made it necessary to expand to Orsay, Nançay, Meudon, and other centers. Through the development of its resources and its openness to the outside world, the École Normale Supérieure laboratory has played a significant role in the revival of French physics.
