Easterbrook came from a military family; his father was Major Edmund P. Easterbrook, of Fort Flagler, Washington.^[2] His sister Gladys Easterbrook [1894-1989] married future general J. Lawton Collins.

Easterbrook was commissioned as a second lieutenant on August 15, 1917.^[3][4] He served originally in 9 Squadron RAF as an observer in Royal Aircraft Factory FE.8s.^[5] He was reassigned to the American 1st Observation Squadron on August 20, 1918. Teamed with pilot William Portwood Ervin in a Salmson 2A2, Easterbrook scored his first aerial victory on October 6, 1918, a double victory on October 8, and his fourth on October 22, 1918.^[6] On November 4, 1918, he became one of the war's last aces.^[7]

During World War II, Easterbrook served on the staff of General H. H. Arnold. Easterbrook later commanded the Air Force's Western Training Command, as well as Santa Ana Air Base in California. On August 21, 1946, he retired as a brigadier general.^[8]

Distinguished Service Cross

The Distinguished Service Cross is presented to Arthur Edmund Easterbrook, First Lieutenant (Air Service), U.S. Army, for extraordinary heroism in action near St. Mihiel, France, September 12, 1918. Because of intense aerial activity on the opening day of the St. Mihiel offensive, Lieutenant Easterbrook, observer, and Second Lieutenant Ralph E. De Castro, pilot, volunteered to fly over the enemy's lines on a photographic mission without the usual protection of accompanying planes. Notwithstanding the low-hanging clouds, which necessitated operation at an altitude of only 400 meters, they penetrated 4 kilometers beyond the German lines. Attacked by four enemy machines, they fought off their foes, completed their photographic mission, and returned safely.^[10]
