Although born in Alabama, d'Olive later lived in Cedar Falls, Iowa. He enlisted into aviation service in Memphis during Bloody April 1917. He trained in France, and was posted to the 93rd Aero Squadron on 23 August 1918^[2] as a SPAD S.XIII pilot. He scored the new unit's first victory on 12 September. The following day, he shot down three Fokker D.VIIs, two in conjunction with George Willard Furlow; it was an exploit that earned d'Olive the Distinguished Service Cross. He scored once more, on 18 October 1918.^[3] Ten days later, he was transferred to the 141st Aero Squadron as a Flight commander.

When d'Olive returned home, he went into business. For reasons that remain murky, d'Olive would not be officially recognized as an ace until 1963. He died of cancer on 20 July 1974.^[4]

In 2016, the USAF Air Force Reserve Command Historian Office commissioned a painting of d'Olive's three-victory flight, unveiling it at an event at the National Museum of the United States Air Force on October 1, 2016.^[5]

A number of historic items and documents from d'Olive's military service are on display at the 93d Bomb Squadron offices at Barksdale Air Force Base, Louisiana.^[6] In 2018, his daughter, Susan d'Olive Mozena, flew on a B-52 training mission with the 93rd in honor of his World War I achievements.^[7]
