Fellows' biographical memoirs

Dr Ken Key FAA was an entomologist distinguished for his work on the ecology and taxonomy of locusts and grasshopphers, leading work to understand the causes of plague locust outbreaks in Australia.

Kenneth Le Couteur was the Foundation Professor of Theoretical Physics at the Australian National University, internationally recognised for his contributions to the statistical model of excited nuclei and to particle accelerators.

Professor Ken Campbell FAA was a leading Australian palaeontologist who mastered fossil invertebrates and pioneered lungfish evolution research, mentoring generations of scientists across a career that spanned almost 70 years.

Professor Kurt Mahler FAA FRS developed a compactness theorem, number classification and 'Mahler's method' for transcendence proofs which remain foundational tools in number theory, geometry of numbers and diophantine approximation.

Lawrence Alexander Sidney (Lawrie) Johnson was a taxonomic botanist notable for the outstanding breadth of his interests and expertise, the rigour of his scientific approach, and the intensity with which he defended scientific conclusions and opinions. His major contributions came through broad synthesis so that systematic studies were integrated with evolutionary and ecological considerations.

Lawrie Lyons was a physical chemist and organic semiconductors pioneer who advanced knowledge of the electronic and electrical properties of molecular crystals. He was the first professor of physical chemistry at the University of Queensland.

Professor Laurie Nichol was a biophysical chemist who specialised in using mathematical tools to understand protein interactions in biological systems. He later served as Vice-Chancellor of the University of New England and the Australian National University.

Dr Lloyd Evans AO FAA FRS was a leading plant scientist who made significant achievements in researching the regulation of flowering and crop production at CSIRO. His work had a major influence on agricultural research and policy.

Robert May was the leading theoretical ecologist of his generation whose mathematical analysis of the stability of ecological communities challenged orthodox views and spawned a new research agenda.

Lou Davies was a radiophysicist who pioneered the manufacture of transistors in Australia and gained international scientific acclaim for his pioneering research on semiconductor devices, bridging academic research and industry.
