OBITUARY

Henry Carroll

Dr Henry Carroll, who has died at the age of 88 (1911-1999), was an international public servant, a veterinarysurgeon and an animal production specialist.

He spent more than 20 years in the service of two United Nations agencies - the Food and A g r i c u l t u r a lOrganisation and the World Health Organisation - consulting in more than 20 countries throughout Africa, SouthAmerica and Europe.

Henry Carroll was born in Sydney, graduated from Hawkesbury with a diploma in agriculture (1930), gained aBVSc from the University of Sydney (1938) and was a foundation member of the Australian College ofVeterinary Scientists.

From 1938 to 1941 he was a veterinary adviser with the proprietary firm, Vita Lick Pty Ltd, and in 1945 hejoined Goldsbrough Mort & Co. in Western Australia as a veterinary adviser. From 1945 to 1953 he travelledwidely in Western Australia and established a strong reputation among the pastoral community for his readinessto go anywhere, any time and to do whatever he could to assist with problems related to animal health andproduction. During this time he wrote Diseases of Sheep in Western Australia and South Australia , published in1949. Later in 1957, in South America he wrote Diseases of Sheep (Enfermedades de los Ovinos), which hadtwo large printings and as recently as 1980 was still in wide use in South American countries. He contributedmost of the articles on foot diseases of sheep in the World Encyclopaedia of Veterinary Science in 1965.

In 1953 he was invited to join the Food and Agriculture Organisation of the United Nations and saw contin-uous service until his retirement in 1974. During this period he served in Brazil (1953-1954), Uruguay (1954),Chile (1955), Peru and Ecuador (1956), Yugoslavia (1957-1958), Ethiopia (1958-1959) and Kenya (1959-1963).He was animal health and production officer for Africa (1964-1966) and was director of the Project of SheepHusbandry Research in Argentinian Patagonia (1966-1971).

During 1971-1972 he was with the UNDP mission to Yemen, and the World Food Program mission to Turkey.His final assignment with FAO was officer-in-charge, sheep production research in north-east Brazil (1972-1974).

In all of these assignments Carroll was known for his hard work, indefatigable dedication to duty and ability toget results in often inefficient and corrupt political administrations. Most notably he was recognised for hisstaunch honour and integrity in all aspects of his professional and personal life.

During World War II Carroll saw service with the Australian Army Veterinary Corps and the Australian ArmyServices Corps. Bestowed with the rank of captain he felt uneasy with his appointed position as what he wouldlater call a “chocolate soldier”. He took the unusual step of applying for a demotion in rank to enable him to givea more real and tangible contribution to the war effort. He was eventually transferred to the Australian ImperialForce with the rank of lieutenant with an independent company whose commitments included deployment onhorse-back in the defence of northern Australia. In 1943 he was officer-in-charge of a farm company to set upfarms in Papua New Guinea to produce food for troops. In 1944 he was transferred to the Royal A u s t r a l i a nArmy Medical Corps to carry out field research in human nutrition, especially ascorbic acid deficiency inPapuans.

In 1981 Dr Carroll received the Kesteven Medal in recognition of his distinguished contributions to interna-tional veterinary science.

He leaves his wife, Gwen, and two sons, John and Charles.
