Frederick Courtice
Image Description
His research has always been concerned with the field of general physiology. With Professor C.G. Douglas at Oxford he studied the effects on respiration and on general metabolism of prolonged muscular exercise; especially was he concerned with the fuel for muscular work: and the part played by such hormones as insulin and adrenaline. Later, in association with Professor H.W.B. Cairns, he studied the effects on cerebral circulation of increased intracranial pressure and of oxygen deficiency. During the war, at the Chemical Defence Experimental Station, he was engaged, with Professors G.R. Cameron, C. Lovatt Evans, J. H. Gaddum and Sir Joseph Barcroft, on many problems concerning the functional disturbances caused by injury and the many toxic agents of Chemical Warfare, and the prevention and treatment of these disorders. This work covered a very wide field of experimental physiology, but one of the main fundamental problems involved was the changes in circulation and fluid balance caused by capillary poisons. Since the war, both at Oxford and in Sydney, he has pursued with his colleagues some of the fundamental problems of fluid balance that arose from investigations with these toxic agents. These investigations have been largely concerned with the physiology of the capillary membrane, with disorders of fluid balance and especially with the functional significance of the lymphatic system and of the plasma proteins and lipids in relation to these disturbances.

Fraser Bergersen
Image Description
Dr Bergersen is distinguished for his research in symbiotic nitrogen fixation. He is a world authority on the physiology and biochemistry of nitrogen fixation in the rhizobium/legume symbiotic system. He was the first to develop methods for preparing active bacteroids from nodules. This led to the purification of nitrogenase components and the identification of the active site on the Mo-Fe-protein. Bergersen was a major contributor in the elucidation of the physiological role of leghemoglobin in nodules supporting efficient respiration at low free oxygen concentrations. His work defined the complex terminal oxidase system in bacteroids. He also contributed information on the structure of legume root nodules, an important recent result being in the localization of leghemoglobin. In current research he is contributing in the bioenergetics of nodule activity and in developing improved techniques for measuring nitrogen fixation in the field.

Shirley Jeffrey
Image Description
Dr S.W. Jeffrey has achieved international eminence in marine science for her detailed and innovative studies of the photosynthetic pigments of plants, especially the planktonic micro-algae. Of particular significance are her discoveries of the chlorophyll c family of pigments, which have major implications, not only for photobiology, but for classifying and defining evolutionary relationships among plants. Her classic work on plant chlorophylls resulted in standard equations widely used for estimating ocean productivity. Her development of novel chromatographic techniques and algal culturing allows new insights into marine productivity. Her pioneering research in mariculture and toxic phytoplankton blooms are of great practical significance for Australia.

Ian Cowan
Image Description
Professor Cowan has made outstanding theoretical and experimental contributions to knowledge of gas exchange in higher plants as influenced by external physical, and internal physiological, processes. His application of control theory has led to a profound understanding of the system in which uptake of carbon dioxide and loss of water vapour are interrelated and regulated through the action of stomata in plant leaves. His hypothesis of optimal control, which represents the way in which the regulation of carbon gain and water loss is modified to withstand drought, is a major step in linking physiological responses to ecological distribution and productivity and has important implications to the adaptation of plants to dry conditions.

David Letham
Image Description
Dr Letham is distinguished for his discovery, naming, and characterisation of the cytokinins, a class of hormones that control cell division and other aspects of development in plants. Of the 20 identified cytokinins now known from higher plants, 15 were isolated, characterised chemically, and unambiguously synthesised by Dr Letham and his colleagues. Cytokinins are now known to be a major class of plant hormones, and their study has become a large branch of plant science, prosecuted world-wide, and stemming from Dr Letham's seminal work. He has used sophisticated techniques of mass spectrometry to elucidate their structure and pathways of metabolism. He and co-workers have also provided the first unequivocal identification of cyclic adenosine monophosphate in higher plants - another significant landmark. He is co-editor of a book on Ribonucleic Acids and a two-volume treatise on Phytohormones, both widely acclaimed.
