Sad news: death of Claude Cohen-Tannoudji

It is with great sadness that we learned of the death of Claude Cohen-Tannoudji, on 22 October.


A leading figure in our scientific community and a former student of Alfred Kastler and Jean Brossel, Claude Cohen-Tannoudji profoundly shaped the history of the LKB and the development of atomic physics. His pioneering work on laser cooling and trapping of atoms earned him the Nobel Prize in Physics in 1997.

Beyond his outstanding scientific contributions, Claude Cohen-Tannoudji was a remarkable teacher. His lectures inspired generations of students and researchers, many of whom went on to pursue research building on his scientific legacy. His influence remains deeply rooted in the history of the LKB and will continue to live on through the research and careers of those he inspired.

Our thoughts are with his family and loved ones during this difficult time.
