Arthur E. Easterbrook was born in Amsterdam, New York on November 4, 1893 to Major E. P. Easterbrook and his wife. He enlisted in the Army in 1917, then transferred to the Air Service in May 1918. He was sent to France and served with the Royal Air Force before being reassigned to the 1st Observation Squadron in August 1918. He flew as an observer on Salmson 2A2 aircraft and according to news reports was the only observer to be credited an ace during the American participation in the war.
