Major General John Stewart Whitelaw, (26 August 1894 – 21 April 1964) was a senior officer in the Australian Army. Whitelaw was a graduate of the first intake of the Royal Military College, Duntroon and served briefly at Gallipoli with an infantry battalion during the First World War. His war service was, however, cut short by a bullet wound suffered during the landing on 25 April 1915 and he returned to Australia where, during the interwar years, he transferred to the artillery and undertook a number of staff and instructional postings. During the Second World War, although he did not serve overseas in an operational role, in his capacity as a senior artillery officer Whitelaw had responsibility for all matters relating to the development of artillery in the Australian Army and in this role he championed the introduction of new technologies and weaponry into the corps and the development of Australian defence industries.
