Hugh McLeod Gordon , (28 March 1909 – 23 April 2002) was a pioneering Australian veterinary scientist and parasitologist. Gordon had a long and distinguished career in veterinary research, becoming a world-renowned expert in the field of veterinary parasitology. Amongst his most important contributions in that field was the discovery that phenothiazine was a safe and effective anthelmintic in sheep and cattle. This discovery, along with the recognition that this compound could be manufactured locally, saved Australian sheep farmers millions of dollars. Early life Hugh Gordon was born in Armidale, New South Wales, Australia to Hugh Hungerford Gordon (1883–1969) of Armidale,; and Frederica Marion Taylor (1885–1962) of "Terrible Vale" Station, Kentucky, NSW. Hugh Hungerford (known as "Bob") was a grazier in the Armidale district of New South Wales, purchasing the property "Elsinore" in 1911. Gordon spent his early years at Elsinore, attending Armidale High School from 1922 to 1926. In 1927 Gordon entered the Faculty of Veterinary Science at the University of Sydney, residing at St. Paul's College. He applied for entry after reading a letter from Professor James Douglas Stewart, Dean of the Veterinary Science faculty, that appeared in the Sydney Morning Herald on 26 January 1927, asking country students to consider veterinary science as a career. Gordon graduated with Honours in 1930 and was awarded the William Cooper & Nephews Prize for Parasitology, and the Baker and Ridley Memorial Prize for Animal Husbandry. He won University Blues for hockey in 1928 and 1929. Marriage and children Gordon married, in 1937, Rita Godfrey Killingley (1908–1996) of Balmain. They fell in love with Manly, settling there following marriage and spending their entire lives there. They had four children, Hugh McLeod (born 1938), David Dunvegan (born 1941), Ian Arthur (born 1943) and Anne Godfrey (born 1949). At the time of his death, Gordon also had seven grandchildren and two great grandchildren. His eldest grandchild (son of Hugh McLeod), Adam Stewart Gordon (born 1967) graduated from the University of Sydney with an Honours degree in Veterinary Science in 1990. At his graduation, Adam wore the gown and hood that Gordon wore at his graduation in 1930. Career Early career Following graduation, Gordon was granted a Walter and Eliza Hall Fellowship to continue postgraduate studies in Veterinary Parasitology. From 1931 to 1933 he worked on parasitic diseases of sheep with Dr (later Sir) Ian Clunies Ross at the McMaster Laboratory of the CSIRO
