Joseph René Bellot (March 18, 1826 – August 18, 1853) was a French Arctic explorer.Bellot was born at Paris, the son of a farrier, but moved to Rochefort with his family in 1831. With the aid of the authorities of Rochefort he was enabled at the age of 15 to enter the Ecole Navale at Brest, in which he studied two years and earned a high reputation. He then took part in the Anglo-French expedition of 1845 to Madagascar, and received the cross of the Legion of Honour for distinguished conduct. He afterwards took part in another Anglo-French expedition, that of Parana to South America, which opened the Río de la Plata to commerce.In 1851 he joined the Arctic expedition under the command of Captain William Kennedy in search of Sir John Franklin. (To harden himself for the Arctic winters, Bellot is said to have allowed himself only a thin mattress and one blanket on bare boards. When he met his first Inuit he endeared himself to them by constructing an artificial leg for a man who was disabled).In February 1852, Kennedy and Bellot set out from their winter quarters in Batty Bay on a dog sledging journey, travelling south to Brentford Bay, where they discovered Bellot Strait (a strait between Boothia Felix and Somerset Island). They then continued west to cross Prince of Wales Island to Ommanney Bay, returning to Batty Bay via Peel Sound and Cape Walker - a total trek of 1,800 km (1,100 mi) (Bellot's narrative of the expedition was published posthumously in 1854).Early in 1852 he was promoted to the rank of lieutenant, and in the same year accompanied the Franklin search expedition under Captain Edward Inglefield. As on the previous occasion, his intelligence, devotion to duty and courage won him wide admiration. While making a perilous journey with two comrades for the purpose of communicating with Sir Edward Belcher, he suddenly disappeared in an opening between the broken masses of ice in the Wellington Channel (August 1853). A memorial grave was built on nearby Beechey Island. A pension was granted to his family by the emperor Napoleon III.The young explorer was mourned widely, and £2,000 was raised after his death of which £500 went towards a granite memorial obelisk (designed by Philip Hardwick and unveiled in 1855) in his memory on the Thames riverside in front of Greenwich Hospital; a nearby Greenwich street, Bellot Street SE10, also carries his name. The remainder of the money went towards supporting his sisters.In 1935 a crater on the Moon was named Bellot in his honour.
