A number of distinguished British-based theoreticians, including Roy Chi s holm, Richard Dalitz, Herbert Frôhlich, John C. Gunn, Peter Higgs, Abdus Salam and Euan Squires, attended a ceremony at the University of Edinburgh in October to mark the retirement of Nicholas Kemmer as Tait Professor of Mathematical Physics. Following Yukawa's first ideas on nuclear exchange forces, Kemmer's work in the 1930s substantially Bill Walkinshaw, applied theoretical Sciulli as Chairman of the Users developed our ideas of the pion.
