Professor Sprung has made major and fundamental contributions to the theory of nuclear matter, of nucleon-nucleon forces, and in the study of real nuclei. His work in 1966 and 1967 on the binding energy and density of nuclear matter is recognized as one of the first accurate calculations in this important but difficult field. He has many later papers in this field. Another pioneering work was his 1969 discovery that, contrary to then accepted ideas, nucleon potentials with very weak repulsive cores can describe experimental data as accurately as those with hard cores; this fact has been widely exploited. Since 1972 he also has studied the properties of real nuclei by Hartree-Fock and Local Density approximations and has developed a new approach suitable for non-spherical nuclei. Dr. Sprung's productivity has remained high (despite being Dean) in both quantity and quality and he has developed an active and fruitful collaboration with students, colleagues and a number of European scientists.

LONG Dr. Standing is internationally renowned for innovations in the field of time of flight mass spectroscopy as applied to the identification and analysis of biomolecules. His work has led to advances in biology, chemistry and biochemistry and to the commercial development of several instruments using techniques developed in his laboratory. He designed and built the first time of flight secondary ion mass spectroscopy (SIMS) apparatus, the first competitive orthogonal-injection electro spray ionization (ESI) instrument and holds a patent on the orthogonal injection matrix-assisted laser desorption (MALDI) technique. He has received several honours from physics and chemistry societies.

By his sympathetic and perceptive teaching, Dr John Mitchell Stedmond inspires generations of students; by his wise counsels, he guides the actions of humane, learned, and professional societies and of the department of English at Queen's University; as an editor, through the "Queen's Quarterly", he brought to the attention of the general public some of the best informed writing in Canada; and, as a scholar by his penetrating analyses of English fiction especially that of the eighteenth century and of Laurence Sterne in particular, he has taught us all to read the most humane part of our literature with new understanding and delight.

Charles Richard Stelck, Professor of Geology at the University of Alberta, has made outstanding scientific contributions in palaeontology, stratigraphy, palaeogeography, and petroleum geology. His world is the North America of late Palaeozoic and Mesozoic times and his researches into what it was like in those times have ranged from detailed descriptions of micro-organisms of the day to the distribution of the ancient lands and seas. He is a recognized authority on the fauna and flora of Cretaceous rocks and his publications on the palaeogeography of western Canada are classics in their field. In practical terms his work has greatly assisted in the development of petroleum resources in northern British Columbia and the Fort St. John gas field. His students in the University of Alberta have contributed widely and successfully in the petroleum industry and in research institutions.

Dr. Stewart is best known for his work on the angular correlation between the gamma rays resulting from the annihilation of slow positrons with electrons in matter. A pioneer in applying this technique to the momentum distribution of electrons in metals, he has continued this study with increasing precision for many years and is now an acknowledged world authority on electrons in solids and liquids. Dr. Stewart has also done important work in the field of neutron inelastic scattering by crystals, and has made some of the standard measurements of the neutron cross-sections of ortho- and para-hydrogen, measurements of prime importance in the theory of nuclear forces. More recently, he has studied zero-point bubbles in solid and liquid helium.
