Philip Roosevelt

Philip James Roosevelt (May 15, 1892 – November 1941) was a World War I Captain for the United States Army, Aviation Section, U.S. Signal Corps (predecessor to the United States Air Force), editor of Aviation and Aeronautic Engineering (later known as Aviation Week, then Aviation Week & Space Technology), banker, yachtsman, and a cousin of United States President Theodore Roosevelt. Philip was close to the president's children and accompanied them on trips. He was a 1912 graduate of Harvard University. He served as the 1914 President of the Harvard Advocate.

He was an original member of the Raynal Bolling’s 1st Aero Company of the New York National Guard. He did not qualify as a military aviator due to his eyesight, but as a military-aviation journalist he was a prominent aerial warfare expert. Immediately after United States Congress declared war on 6 April 1917, the Signal Corps summoned Roosevelt to Washington to help plan the aviation mobilization. He impressed Benjamin Delahauf Foulois and accompanied him to France. Foulois paired Roosevelt with major Bert Atkinson, but they had the command organization that resulted from the American Expeditionary Force’s inexperience in coalition warfare. They operated under the French Sixth Army, but two different American headquarters (including Colonel Billy Mitchell's 1st Air Brigade headquarters) felt that they held jurisdiction. The two planned America’s first-ever air-land battle at a time when the US Army was still learning the nuances of command relationships between the pursuit and observation groups and the corps and armies they supported.
