Claude Cohen Tannoudji

It is with great sadness that the Les Houches School of Physics has learned of the passing of Claude Cohen-Tannoudji, recipient of the 1997 Nobel Prize in Physics, at the age of 93. Deeply attached to our School, he first participated as a student in 1955—an experience that proved decisive in shaping his vocation as a physicist. He later returned on several occasions as an professor, notably co-directing the 1964 session dedicated to quantum optics and quantum electronics. A brilliant scientist and an exceptional educator, he embodied the values ​​of passing on and sharing knowledge that lie at the very heart of the "Les Houches spirit." L'Ecole de Physique des Houches wishes to pay a heartfelt tribute to him.
