Gordon McClymont, Australian ecologist and academic (b. 1920)
Gordon Lee McClymont AO (8 May 1920 – 6 May 2000) was an Australian agricultural scientist, ecologist, and educationist. The originator of the term "sustainable agriculture", McClymont is known for his multidisciplinary approach to farm ecology. McClymont was the foundation chair of the Faculty of Rural Science at the University of New England, the first degree program of its kind to integrate animal husbandry, veterinary science, agronomy, and other disciplines into the field of livestock and agricultural production. In 1978, in recognition of his work and contributions to his field, he was appointed Officer of the Order of Australia.

Born in Australia, McClymont entered the University of Sydney under the sponsorship of the New South Wales Department of Agriculture. After graduating with a bachelor's degree in veterinary science from Sydney and a PhD from the University of Cambridge, he worked as an animal nutrition researcher for the state of New South Wales. Believing that his education had not adequately prepared him for his work, McClymont designed a broader, multi-disciplinary educational approach to the field of livestock and agricultural production. Impressed with his ideas, the University of New England hired McClymont in 1955 to chair its new department of rural science.

While at the university, McClymont championed his approach to farm and livestock production and sustainability of agricultural ecosystems. Under his direction, the University of New England became a leader in ruminant research. The Australian poultry industry recognized McClymont's contributions to poultry production with a special award in 1967. After his retirement in 1980, McClymont continued to work with the agricultural industry in Australia and consulted with the United Nations and the World Bank on farm issues. In 1996, he expounded his approach to livestock and farm production in the book Rural Science: Philosophy and Application.
