Irish-born Dr Elizabeth Nesta Marks was an eminent Queensland entomologist whose breakthrough work with mosquitoes and malaria in the 1940s and 1950s was of international importance. Dr Marks, who was generally known as Pat, migrated to Brisbane with her family from Ireland in 1920 and completed her Bachelor of Science at the University of Queensland in 1938. Dr Marks was appointed a Graduate Research Assistant to the newly formed Mosquito Control Committee (MCC) at the University of Queensland in 1943. During the War, she uncovered the breeding behaviour of many mosquitoes, including Aedes culicformis, using specimens from Cape York. From 1949 to 1951, Dr Marks studied at the University of Cambridge, attaining her PhD in 1951. She produced more than 100 papers describing 38 previously unknown species of mosquito as well as new species of other insects including fruit flies, bugs, cockroaches and ticks. Her major publications include the Atlas of Common Queensland Mosquitoes (1966) and the 12 volume set The Culicidae of Australasia (1980-1989). After the MCC closed in 1973, Dr Marks moved to the Queensland Institute of Medical Research where she was appointed as Principal Entomologist. She retired in 1983 but continued her research at the Institute after her retirement. She was also actively involved in local Queensland history which lead her to become a notable figure at Brisbane History Group seminars and functions and an active member of the Samford District Historical Museum Society.
