Remembering Yuri Ryzhov

Academician Yuri Alekseevich Ryzhov (28 October 1930, Moscow – 29 July 2017) 

Academician Rizhov was a very sensible and warm personality. He has been for long time the Chair of the Russian Pugwash Committee. He represented the original spirit of Pugwash, focused on avoiding nuclear risks and promoting reciprocal understanding between Russia and the West. He was very much supporting what we can call democratic values across the boundaries. His departure saddens us, but his memory is a powerful reminder of what Pugwash was meant to be and still is meant  to be. I wish to express to his entire family and all his friends the deep condolences of the Pugwash community.
