James Hamilton 1918-2000
We are sad to report that James Hamilton died in Cambridge, England in July. Born in Sligo, Ireland, James Hamilton got his MSc at Queen's University, Belfast on the eve of World War II. He received his PhD from Manchester University in 1948, and then moved to a position as University Lecturer in Mathematics and Fellow of Christ's College at Cambridge University (1950-60). Hamilton was Professor of Physics at University College, London for a few years (1960-64) before joining the Nordic Institute for Theoretical Physics (NORDITA) in Copenhagen. As NORDITA Professor of elementary particle physics he shaped the institute's research in the field during a crucial period and trained a whole generation of young Nordic physicists. During a period before his retirement at the end of 1985 Hamilton also served as NORDITA Director. He spent an active retirement in Cambridge, continuing with his research and frequently visiting DAMTP.
After early work on problems related to the interaction of radiation with atoms, James Hamilton turned to high energy physics and produced the well-known treatise "The Theory of Elementary Particles" (Oxford, 1959). His interests centered on S-matrix theory and he had a leading role in the efforts to understand the structure of resonances and scattering amplitudes using unitarity and analyticity. Some of his results are summarized in his book with B. Tromborg, "Partial Wave Amplitudes and Resonance Poles" (Oxford, 1972).

Probably the most important contribution to physics by James Hamilton was his development of sophisticated techniques for making very precise amplitude analyses of low energy hadronic interactions, notably of the pion nucleon interaction. Here, using dispersion relations among other tools, he and his collaborators were able to improve on the art of phase shift analysis, and thereby helped pave the way to a better understanding of reaction mechanisms and crucial con-cepts such as Finite Energy Sum Rules and Dolen-Horn-Schmidt-duality. His insistence on such sophisticated analysis formed a school which he took with him to Scandinavia and Nordita. He strongly cared for the young Nordic fellows he was to guide.

James Hamilton had a life-long interest in mathematical aspects of elementary particle physics and questions related to causality. He continued to work on these questions during his retirement in Cambridge and published the book "Aharonov-Bohm and Other Cyclic Phenomena" (Springer, 1997) just a few years before his death.

Jim Hamilton left an important legacy in elementary particle physics.
His friendly spirit will be warmly remembered, particularly by his students and colleagues in the Nordic countries and in Britain.
