American Arctic explorer, born in Chicago, IL, on the 30th of September 1849. He graduated from the United States Naval Academy in 1870; served on the Portsmouth on a surveying expedition in the Northern Pacific; took part in subduing an insurrection at Honolulu, HI, in 1873; served on board the Vandalia when General Grant visited Egypt, and in 1878 joined the Jeannette, which sailed from Havre, France, on an Arctic exploration. The expedition sailed through Bering Straits, and cruised in the Arctic Ocean until the steamer was crushed in the ice. The crew marched for 95 days over the ice, dragging their boats, and then embarked in the open waters, but a storm arose and separated the boats. Lieutenant Danenhower’s boat reached the Lena delta, September 17, 1881, but the other crews perished. With his crew he arrived in America in June 1882. He published The Narrative of the Jeannette (1882). He died in Annapolis, MD, on the 20th of April 1887.
