Rear Admiral John Saumarez Dumaresq CB, CVO (/dᵿˈmɛərᵻk/ duu-MAIR-ik; 26 October 1873 – 22 July 1922) was an officer in the Royal Navy. He served during the First World War but is most remembered as an inventor, for development of the device named after him, the Dumaresq, which helped users calculate the rate at which the range to an enemy ship was changing over time. He was the first Australian born officer to command the Australian Fleet.
Dumaresq was the grandson of a British settler who had originally gone to Australia accompanying the Governor of New South Wales, Ralph Darling in 1825. In 1907 he married Christian Elizabeth Louisa Dalrymple.
He lived in England from age two and became a naval cadet at HMS Britannia in 1886. He became interested in torpedoes and gunnery and introduced a number of innovations. In 1904 he was promoted to commander. In 1908 he commanded a flotilla escorting King Edward VII on a tour of Russia and was appointed a Member of the Royal Victorian Order from the King and awarded the Order of Saint Catherine from the Tsar. On 30 June 1910 he was promoted to captain, working on fire control equipment at the Royal Navy war college at Portsmouth.
