Edmund Pike Graves (March 13, 1891 – November 22, 1919) was an American aviator, Royal Flying Corps and Polish Air Force officer, the latter as a member of the Polish 7th Air Escadrille "Kościuszko Squadron", who served as an instructor and a fighter pilot during World War I and the Polish-Soviet War.
Later, he was assigned as an instructor in aerial gunnery at the United States Army Air Service training facility at Camp Taliaferro, Hicks Field, Fort Worth, Texas.
In early spring, 1918 he was transferred to the Officers' School of Special Flying at Armour Heights, Toronto, Ontario, where he was promoted to 1st lieutenant in May, 1918.
After being demobilized from the Canadian RFC in July, 1919, he volunteered for the Kościuszko Squadron in the newly established Polish Air Force on October 12, 1919, and flew Albatross aircraft based out of the Lewandówka airfield in Lwów (now Lviv, Ukraine), on patrols and scouting missions, over the front lines during the Polish-Soviet war.
Merian C. Cooper, another American member of the Kosciuszko Squadron (and later famous film director) described him in his book as follows:[2] Lieutenant Graves took off into the sky.
Unfortunately, while performing acrobatics over the city in an Albatros D.III fighter, he had an accident: his aircraft lost its right wing during a double roll at 150 feet (46 m).
