Sir Edward Augustus Inglefield (27 March 1820 – 4 September 1894) was a Royal Navy officer who led one of the searches for the missing Arctic explorer John Franklin during the 1850s. In doing so, his expedition charted previously unexplored areas along the northern Canadian coastline, including Baffin Bay, Smith Sound and Lancaster Sound. He was also the inventor of the marine hydraulic steering gear and the anchor design that bears his name. bears his name, as do the Inglefield Land region and the Inglefield Gulf of Greenland. Career First voyage to the Arctic Inglefield set out from Britain on his search in July 1852, commanding Lady Franklin's private steamer , seven years after Sir John Franklin had left on his ill-fated search for the fabled Northwest Passage. Once Inglefield had reached the Arctic, a search and survey of Greenland's west coast was made; Ellesmere Island was resighted and named in honour of the president of the Royal Geographical Society. Smith Sound was penetrated further than any known records; Jones Sound was also searched; and a landing was made at Beechey Island in Lancaster Sound. No sign, however, of Franklin's expedition was found. Finally, before the onset of winter forced Inglefield to turn homewards, the expedition searched and charted much of Baffin Island's eastern coast. Despite finding no traces of the Franklin expedition, Inglefield was fêted on his return for the surveying his expedition had achieved. The Royal Geographical Society awarded him its 1853 Patron's Medal "for his enterprising survey of the coasts of Baffin Bay, Smith Sound and Lancaster Sound." Subsequent Arctic voyages Inglefield made two further voyages to the Arctic in , to supply the search for the Franklin expedition overseen by Sir Edward Belcher. He returned from the first of these in 1853, bringing with him the first officer to have traversed the Northwest Passage, Samuel Gurney Cresswell of . The Investigator had also been sent to join the search for the Franklin expedition, but starting from the western side of northern Canada. Arriving back in the Arctic the following year, 1854, Inglefield found Belcher's ships abandoned, save one to which the crews had retreated. Most of these men returned with Inglefield to Britain. Later life Soon after his return from the Arctic, Inglefield was sent to join the Crimean War in the Black Sea as captain of HMS Firebrand, where he took part in the siege
