Frank Fenner  Frank John Fenner (21 December 1914 – 22 November 2010) was an Australian scientist with a distinguished career in the field of virology. His two greatest achievements are cited as overseeing the eradication of smallpox, and the control of Australia's rabbit plague through the introduction of Myxoma virus. The Australian Academy of Science awards annually the prestigious "Fenner Medal" for distinguished research in biology by a scientist under 40 years of age. Frank Johannes Fenner was born in Ballarat in 1914, but the family moved to Adelaide, South Australia in November 1916. Frank attended Rose Park Primary School and Thebarton Technical School. He attended the University of Adelaide, where he earned degrees in medicine and surgery in 1938. That year, uneasy about Hitler's rise, he legally changed his middle name to John. From 1940–1946 he was a Captain and Major in the Australian Army Medical Corps with service in Australia, Palestine, Egypt, New Guinea, and Borneo, as medical officer in field ambulance and casualty clearing station, pathologist to general hospital, and malariologist. For his work in combating malaria in Papua New Guinea he was made a Member of the Order of the British Empire in 1945. Following his war-time service he was recruited by Frank Macfarlane Burnet to work at the Walter and Eliza Hall Institute of Medical Research in Melbourne. Initially they worked on smallpox in mice, for which he coined the term 'mousepox,' and later on poxvirus genetics. In 1949 he received a fellowship to study at the Rockefeller Institute for Medical Research in New York City, he worked on mycobacterium Bairnsdale bacillus, which causes Buruli ulcer, the third most important mycobacterial disease worldwide after tuberculosis and leprosy. Here he worked with and was influenced by René Dubos, who is one of the claimed originators of the phrase "Think Globally, Act Locally". Returning to Australia in 1949, he was appointed Professor of Microbiology at the new John Curtin School of Medical Research at the Australian National University, Canberra. Here he began studying viruses again, in particular the myxoma virus. Throughout the 1940s and 1950s Australia had severe rabbit plagues. Fenner's work on the myxoma virus showed that initially it killed rabbits in 9 to 11 days and was 99.5% lethal. Under heavy selection pressure, the few rabbits that survived developed resistance, which meant that the pest was never completely eradicated, but their numbers were reduced.
