Sir Geoffrey Arthur Romaine Callender (b. November 25, 1875 at Didsbury, Manchester, England; d. November 6, 1946 in Greenwich, London, England) was a naval historian. He studied modern history at Oxford University's Merton College and became a professor at the Royal Naval College, Osborne, in 1905. While at Osborne, Callender produced the three-volume naval history textbook Sea Kings of Britain (1907-1911), and in January 1913, he was promoted to the head of the history and English department. In 1920, Callender became both the secretary and treasurer of the Society for Nautical Research, positions he held until his death. He left Osborne in 1921 to head the history department of the Royal Naval College, Dartmouth, and in 1922, Callender was appointed chair of history at the Royal Naval College, Greenwich. Two years later, he published The Naval Side of British History. In the early 1920s, Callender was also heavily involved in the Society for Nautical Research's successful campaign to preserve the HMS Victory. After helping to save the HMS Victory from utter destruction, Callender set his sights on a naval museum to preserve and display Britain's naval history. Following the passage of the National Maritime Museum Act in 1934, Callender became the institution's first director.
