Katherine Stinson (February 14, 1891, in Fort Payne, Alabama- July 8, 1977, in Santa Fe, New Mexico). She was the fourth woman in the United States to obtain a pilot's certificate, which she earned on July 24, 1912, at the age of 21. Initially, she planned to get her certificate and earn money she earned from exhibition flying to pay for her music lessons. However, she found she liked flying so much that she gave up her piano career and decided to become an aviatrix. Wikipedia
