On 25 June 1831 the committee met. The chair was taken by Major General Sir Howard Douglas, in his person a symbol of the "United Service": a soldier who was the leading expert on naval gunnery. The resolution that the institution be established was put by the future Field Marshal Viscount Hardinge and seconded by the future Rear-Admiral Sir Francis Beaufort, the famous hydrographer. The first name adopted was the Naval and Military Museum: this was altered in 1839 to the United Service Institution, and in 1860 to the Royal United Service Institution by a royal charter of incorporation. In 2004 the name was changed to the Royal United Services Institute for Defence and Security Studies. Fellows of RUSI may use the five-letter post-nominal abbreviation, FRUSI.
