Abstract

In July 1990 a meeting on Quantum Structures was held in Adelaide. The meeting was in honour of Ian Ellery McCarthy on the occasion of his sixtieth birthday. Ian, who is currently Professor of Physics and Associate Director of the Electronic Structure of Materials Centre at Flinders University, has had an enormous influence on the development of physics and physicists within Australia. He has always been interested in and active in promoting good physics and good young physicists. He was also instrumental in establishing the physics department at Flinders University and ensuring that it was very successful in its research activities. Those of us who have known Ian for some time have always admired him for his great enthusiasm for physics, for Australian Rules Football and for life in general.
