Claire Lee Chennault was born on September 6, 1890, in Commerce, Texas. Chennault spent his early years in Louisiana, attended Louisiana State University, and joined the ROTC. He worked as a school principal until the outbreak of World War I, at which point he joined the Army Signal Corps. Chennault went on to fly with the Army Air Service during that war. After World War I, Chennault was made Chief of Pursuant Section at the Air Corps Tactical School. He also led the 1st Pursuit Group Army Air Corps aerobatic team, the Three Musketeers, which he later reorganized as the Three Men on the Flying Trapeze. By the mid-1930s, Chennault’s health was suffering and he fought with superiors after he was passed over for a promotion. So he retired from the military on April 30, 1937. He was then invited to join a small group of American civilians in China training their airmen.
