The book compiles a memoir and primary documents about an American aviator who embraced early aeronautics, left a legal career to volunteer for France during the First World War, and helped organize American flyers into a distinct squadron. It traces his privileged upbringing, education, and technical enthusiasm for flying, then recounts his training, combat exploits, and ultimate sacrifice. Selections of his own writing, letters, and family correspondence are presented alongside tributes from comrades and official condolences. Illustrations and appendices document his machines, decorations, and the squadron’s early history.
