De Haven Edwin 
(07.05.1816–01.05.1865)

American arctic explorer. 
Born in Philadelphia, at the age of ten he began service in the navy as a midshipman, in 1841 he was promoted to lieutenant, in 1857 he was forced to resign due to a sharp deterioration in his vision. Having lived a short life, De Haven nevertheless managed to inscribe his name in the history of studies of the American Arctic and Antarctic. 
During 1839–1842 He participated in the C. Wilkes Antarctic Expedition, but the main activity of his life was the Arctic navigation of 1850-1851. in order to search for the expedition of J. Franklin. 
Expedition De Haven on two ships "Advance" and "Rescue", purchased and equipped with G. Grinnell, was named the First Grinnell. Grinnell and De Haven unanimously decided that small compact ships are better suited for navigation in the Arctic, often winding, with narrow fairway straits of the Canadian Arctic archipelago. They turned their attention to two miniature brigantines, which had a displacement of 144 and 91 tons, respectively. Participating in the expedition as a physician and naturalist, E. Kane expressed his impression of the ships in this way: “They seemed to me more like a pair of schooners for coastal navigation than a national squadron equipped to a distant and dangerous sea”. With Grinnell's money, a great deal of work was done on retrofitting vessels and adapting them to swimming in ice. The boards were reinforced with a 2.5-inch-thick oak paneling, the noses were reinforced with metal sheets, the frames were strengthened, additional props were installed, etc. The expedition was perfectly equipped, the teams consisted of young, but very brave and energetic sailors. The instruction given to De Haven was written in short, clear and definite phrases and contrasted sharply with the lengthy instructions of the English Admiralty. However, it also clearly showed confidence that Franklin should be sought in the west or north from the Lancaster and Barrow straits, confidence that delayed the clarification of the fate of the Franklin expedition for years and certainly cost the lives of many of its participants. 
They left New York on May 24, 1850, from the Strait of Barrow climbed north along the Wellington Strait, discovered an unknown land, which was called the Grinnell Land. Subsequently, it became clear that this is the peninsula of Devon Island. Expedition succeeded simultaneously with a detachment of E. Ommanney from the expedition of G. Austin found on Beachy Island is the site of the first wintering of the ships of Franklin.

After returning from this voyage, which lasted 16 months, De Haven transferred to the coastal service at the Naval Observatory. 
He  died in Philadelphia.  He was buried in the Church of Christ (Christ Church) in Philadelphia.
