He worked primarily on physical chemical studies of the purification and electro-deposition stages of zinc production. Research into hydrometallurgical procedures to extract lead from zinc plant residue earned him the Hofmann Prize in 1971. In his leisure time, Bratt became an expert on Tasmanian lichens. He was inspired to study lichens when he met Peter James, Lichenologist at the Natural History Museum in London, both being participants in the British Glaciological Society expedition to Patagonia in the late 1950s. On returning to Tasmania after his PhD studies, Bratt started investigating the local lichen flora, collecting specimens on his many travels to remote parts of the state. He assembled a large herbarium at his home. As Honorary Research Associate in the Department of Botany at the University of Tasmania from 1969 he curated the Tasmanian Lichen Herbarium. Bratt's bushwalking activities were curtailed when he developed kidney failure in 1974. His collection of over 15,000 specimens was bequeathed to the Tasmanian Herbarium. 1952 1952 Education - Bachelor of Science (BSc), University of Tasmania 1952 1955 Career position - Research Scientist, Electrolytic Zinc Company of Australasia 1957 1958 Career position - Member, Imperial College Exploring Society Karakorum Expedition, Mongolia 1958 1959 Career position - Member, British Glaciological Society expedition to Patagonia 1959 1959 Career event - Joined the Royal Geographical Society 1959 1959 Career position - Leader, Imperial College Exploration Society expedition to the Peruvian Andes 1959 1959 Education - PhD, Imperial College, London 1959 1977 Career position - Research Scientist (later Senior Principal Research Officer), Electrolytic Zinc Company of Australasia 1965 1977 Award - Life Member, Royal Society of Tasmania 1969 1977 Career position - Honorary Research Associate, Department of Botany, University of Tasmania 1971 1971 Award - Hofmann Prize for extractive metal (shared with R.
