Michiji Konuma (Pugwash Japan)

Toshiyuki Toyoda, a Japanese physicist and a Pugwashite, died on 15 May 2009 in Tokyo at the age of 89. He worked for Pugwash as a Council member from 1975 to 1987. He helped Hideki Yukawa and Sin-itiro Tomonaga organizing the 25th Pugwash Symposium "A New Design towards Complete Nuclear Disarmament" and organized the 56th Pugwash Symposium "Peace and Security in the Asia-Pacific Region". He attended 26 Pugwash meetings in total from the 7th Conference held at Stowe, USA in 1961 to the 45th Annual Conference held at Hiroshima, Japan in 1995.

For many years Toyoda was a member of the Board of Sponsors for Bulletin of the Atomic Scientists. He worked on theoretical nuclear and elementary particle physics. He was Professor Emeritus of Nagoya University. He served as Director of the Peace Research Institute of Meiji Gakuin University, Tokyo.

Toyoda published many articles and books on physics and on issues concerning nuclear weapons including "Criticism on Nuclear Strategy". The funeral ceremony will be held in Tokyo on 21 May 2009.

Picture is the cover of the book edited by William Epstein and Toyshiyuki Toyada following the 1975 Kyoto Pugwash Workshop, August 28 to September 1 1975. The symposium dealt with the subject ‘A New Design Towards Complete Nuclear Disarmament: The Social Function of Scientists and Engineers.’ Spokesman Books, 1977.

You can read an interesting article here by Prof. Toyoda, "Scientists Look at Peace and Security", Bulletin of the Atomic Scientists, Vol 40, No. 2, February 1984, pp 16 - 19. The article outlines the post War movement among scientists in Japan, and mentions the role of leading Japanese Pugwashites, such as Hideki Yukawa and Sin-itiro Tomonaga. Toyoda concludes the article by saying,

"The role of conscientious scientists in Japan is...becoming more important than ever."
