George Eugene Belknap (22 January 1832 – 7 April 1903) was a rear admiral in the United States Navy. USS Belknap (DD-251) was named for him.
Born in Newport, New Hampshire, Belknap was appointed a Midshipman in 1847. He commanded the monitor during the attacks on Fort Fisher, and the sloop-of-war during the Formosa Expedition of 1867. Belknap was the senior officer present during the riots following David Kalākaua's election as the King of Hawaii in 1874. At the time, he was serving as commander of the sloop-of-war on a mission to take deep-sea soundings in the North Pacific to help identify the best route for a submarine cable between the United States and Japan.
Belknap commanded the United States Naval Observatory from 1885 to 1886 and the Mare Island Naval Shipyard from 1886 to 1890. Belknap was appointed as a rear admiral on 12 February 1889. He served as the Commander of the Asiatic Squadron from 4 April 1889 to 20 February 1892. He retired from the Navy on 22 January 1894.
In August 1902, Belknap and his wife visited the United Kingdom, including Devonport as guests of Rear Admiral William Hannam Henderson, the Admiral Superintendent of the dockyard.[1]
Belknap and his wife lived in Brookline, Massachusetts after his retirement. On 7 April 1903, he died at Key West, Florida while on a working vacation to advise the Navy Department on a potential naval base location.[2] On 13 April 1903, Belknap was buried with full military honors at Arlington National Cemetery. The funeral procession from St. John's Episcopal Church was accompanied by two battalions of U.S Marines and one battalion of U.S. Army engineers.[3]
Belknap was a member of the Grand Army of the Republic, a Veteran Companion of the Military Order of the Loyal Legion of the United States (MOLLUS) and an Honorary Companion of the Military Order of Foreign Wars. He was also a member of the New Hampshire Society of the Sons of the American Revolution.
A portrait of Admiral Belknap is on display in Luce Hall at the United States Naval War College in Newport, Rhode Island.
He was the father of Rear Admiral Reginald R. Belknap who served as national Commander-in-Chief of MOLLUS from 1947 to 1951.
