It is sad news to hear of Sergey’s death, but he left us with many great contributions and much to celebrate in his life. He was a major figure in Russian and European regional science. Sergey was a brilliant scholar and organizer. He was leading person of the work of the Russian–Hungarian regional science cooperation, started in the middle of 1980s when we first met. He was very helpful in the meetings both in Russia and in Hungary. Results were for our research communities to be able to engage in the emerging, and then real debates about the futures of regional economic and social problems. A lot of publications of Hungarian journals, edited books and conference proceedings keep his name. We are very thankful to him for these achievements. He made a lot for distributing spirit of regionalism and knowledge of regional science.  He was always the most urbane and modest man, but very supportive and encouraging. I am sure your institute and the other organisations to which Sergey contributed will all recognise his contribution and will be very grateful for his inputs and support. Please pass on my condolences to his family and former colleagues.

We will never forget Sergey.
