Krzysztof Gawędzki, emeritus CNRS research director at the École Normale Supérieure (ENS) in Lyon and member of the SRS Scientific Council, died on Friday, January 21, 2022, at the age of 74.

Krzysztof obtained his PhD in 1971 under the supervision of Krzysztof Maurin at the University of Warsaw, where he stayed until 1979. After a brief stay in Harvard University, he emigrated to France in 1981. He was a CNRS research director at IHES from 1984 to 2001, before joining the ENS in Lyon.

He was the recipient of the 2022 “Dannie Heineman” prize for mathematical physics “for fundamental contributions to quantum field theory, statistical mechanics, and fluid dynamics using geometric, probabilistic, and renormalization group ideas.”

His broad knowledge in mathematical physics conferred him a leading role in the domain.

Our thoughts are with his family, friends and colleagues.
