"1915 The American Amateur Trapshooting Association (AATA, 1916-1919) formed on December 23, 1915 with John Philip Sousa as president. This was the first attempt to have a national organization organized and run by amateurs. Sousa would serve as president again in 1918. This new association was the first attempt at amateur control and did not replace any other organization. It co-existed at the time with the Interstate Trapshooting Association."
"1919 The AATA was disbanded and absorbed by the newly formed American Trapshooting Association."
