Henry Aloysius Petre, DSO, MC (12 June 1884 – 24 April 1962) was an English solicitor who became Australia's first military aviator and a founding member of the Australian Flying Corps, the predecessor of the Royal Australian Air Force. Born in Essex, Petre forsook his early legal career to pursue an interest in aviation, building his own aeroplane and gaining employment as an aircraft designer and pilot. In 1912, he answered the Australian Defence Department's call for pilots to form an aviation school, and was commissioned as a lieutenant in the Australian Military Forces. The following year, he chose the site of the country's first air base at Point Cook, Victoria, and established its inaugural training institution, the Central Flying School, with Eric Harrison.
