On June 25, 1918, 20-year-old Quentin Roosevelt wrote to his mother from his station in France, saying: “I am now a member of the 95 th Aero Squadron. I’m on the front! Cheers, oh cheers, and am very happy.” He had dropped his Harvard studies to become a fighter pilot in the Great War, in the US expeditionary force in France, where his three older brothers also served.
