Lockwood was born in
Annapolis, Maryland, to
Henry Hayes Lockwood and his wife Anna. He attended
St. John's College. He was commissioned
second lieutenant in the
23rd Infantry of the
United States Army in October 1873. He was promoted to first lieutenant in March 1883. In 1881, Lockwood signed up for the
Lady Franklin Bay expedition under
Adolphus W. Greely, and was accepted as second-in-command. During this three-year expedition, Lockwood led a sledging party, with
David Legge Brainard, to Mary Murray Island, off northern
Greenland, at a latitude of 83° 24', thus breaking the British record of the time for the most northerly point reached. In 1883, he crossed
Grant Land, reaching the western shore of
Ellesmere Island. He died at
Cape Sabine in April 1884, along with several other members of the party, before rescue arrived on June 22, and was buried at the
United States Naval Academy Cemetery.
Lockwood Island in northern Greenland was named in his honor. == References ==
