Cook was born on 23 September 1897 in Bexhill, Sussex, England. His mother was Emily, and he had an older brother, Errol Aufrere, who was born in 1895. His father, James Whiteford Murray Cook, moved to Australia soon after Cecil was born, and the family followed in 1900 to live in Barcaldine, Queensland. Dr James Cook became the Lodge doctor in Barcaldine and he was medical superintendent of the Victoria Hospital, positions he held for thirty years. He was very well regarded, credited with bringing Victoria Hospital "into a new era of respectability and service to the public". Cook attended the Barcaldine State school for 1906-8 and was then a boarder at The Southport School, where he was the dux in 1914. He studied medicine at the University of Sydney, living at St Andrew's College, and he graduated with MB, Ch.M. in 1920, MD in 1929, and DPH in 1931.
As part of his MD studies, Cook conducted a major epidemiological study of leprosy in Australia. He published this report as his MD thesis The Epidemiology of Leprosy in Australia in 1927. The newly established Federal Health Council subsequently adopted leprosy as one of its concerns.
Northern Australia Appointment
He was appointed the Chief Medical Officer, Chief Health Officer, Chief Protector of Aborigines and Quarantine Officer for North Australia on 1 March 1927. For the first six months he was the only medical practitioner in the state, and after that he focused on establishing a public health system. From 1929 to 1939, he established general hospitals at Katherine, Tennant Creek and Alice Springs, a hospital outside Darwin to treat leprosy, a training school for nurses, a tuberculosis clinic, a medical benefit fund, he commenced infant welfare services, and he founded the Nurses’ Board of North Australia. In 1934 he joined forces with Dr Clyde Fenton to launch the Northern Territory Aerial Medical Service under the umbrella of the Australian Aerial Medical Service, which later became the Flying Doctor Service. In 1930, he took leave to study anthropology and public health in Sydney.
Racial views and controversy
Growing public criticism of the exploitation and abuse of Aboriginal peole led to passing the Aboriginals Protection and Restriction of the Sale of Opium Act 1897 in Queensland. This Act created the first official state control of Indigenous Australians in Queensland, including health. It authorised establishment of government reserves for Aboriginal people, and it led in 1904 to the appointment of a Chief Protector of Aborigines within the department of the Home Secretary. However its aims of protecting Aboriginal people were not realised: overcrowding, inadequate provisions and housing led to mortality rates which peaked at 13 per cent annually. While there were some improvements during the 1920s and 1930s, they remained triple the national average. Cook irritated Alice Springs residents by urging them to allow Aboriginal patients in a proposed hospital and by allowing a Catholic mission. He also sought to protect "full-bloods" from unauthorised visitors. However, he generally opposed church missions and favoured assimilation. Hence, when it came to Aboriginal people he argued for "breeding them out" and stated: He also instituted the "dog tag" system of fingerprinting and medical examination of Aboriginal people.
Personal life
Cook married Jessie Winifred Miller on 4 March 1924; Jessie died in 1978.
