"George Carson-Cooling (1896-1960), headmaster, was born on 31 May 1896 at Milton, Brisbane, a twin and sixth child of John Arthur Cooling, a clerk from England, and his Irish-born wife Sara, née Kennedy. A scholarship boy at Brisbane Grammar School, in his third year there George won the Earl of Meath Challenge Cup in an essay competition open to all school students in the British Empire. Proceeding to the University of Queensland (B.Sc., 1918; M.Sc., 1920), on 7 December 1917—only days after his final undergraduate examinations—he enlisted in the Australian Imperial Force. He reached the Western Front in October 1918, by way of Egypt and England, and was posted to the 5th Divisional Artillery. Promoted to extra regimental sergeant in March 1919 and given educational duties, he taught Australian soldiers awaiting demobilization. He was discharged in Brisbane on 13 August 1919."
