James B. Lockwood

James Booth Lockwood (October 9, 1852 – April 9, 1884) was a United States Army officer and arctic explorer.

Biography
Lockwood was born in Annapolis, Maryland, to Henry Hayes Lockwood and his wife Anna. He was commissioned second lieutenant in the United States Army in October 1873. 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.
