As aviation pioneers, the members of the Stinson family helped fuel the early growth of aviation in Texas. In 1912 Katherine became the fourth licensed female pilot in the United States and was known as a death-defying stunt aerialist. Two of her siblings, Marjorie and Eddie, operated the Stinson School of Flying in San Antonio, Texas, one of the first in the nation to train World War I pilots. The field adjacent to the school became what is known today as Stinson Municipal Airport. In 1920, Eddie founded the Stinson Aircraft Corporation which manufactured thousands of light planes over several decades.
