Louise Thaden

Iris Louise McPhetridge Thaden (born Louise McPhetridge; November 12, 1905 – November 9, 1979) was an American aviation pioneer, holder of numerous aviation records, and the first woman to win the Bendix trophy, alongside Blanche Noyes. She was inducted into the Arkansas Aviation Historical Society's Hall of Fame in 1980.

Louise McPhetridge was born in Bentonville, Arkansas, and attended Bentonville public schools. McPhetridge attended the University of Arkansas in Fayetteville, Arkansas, from 1921 to 1926 and studied as a journalism, physical education, and pre-medical major.

In 1926, McPhetridge was working for the J.H.J. Turner Coal Co. where one of her main customers was the Travel Air Corporation in Wichita, Kansas, owned by Walter Beech. Beech liked McPhetridge and offered her a job as a sales representative in San Francisco, California, which she accepted. Her salary included free pilot's lessons, and she earned her pilot's certificate in 1928. She was the first female pilot to be licensed by the state of Ohio.

McPhetridge met Herbert von Thaden, who was a United States Army Signal Corps pilot and engineer who worked on developing the first American all-metal aircraft, the Thaden T-2. McPhetridge and von Thaden were married in San Francisco on June 19, 1928. By 1929, Louise Thaden had become only the fourth woman to hold a transport pilot rating.

Thaden rapidly became a major figure in the aviation world and set many world performance records and won many major flying events. In 1929, she became the first pilot to hold the women's altitude, endurance and speed records in light planes simultaneously. Thaden set the women's altitude record in December 1928 with a mark of 20,260 feet. In March 1929, she set the women's endurance record with a flight of 22 hours, 3 minutes, 12 seconds.

Following the fatal crash of Florence Klingensmith at the 1933 International Air Races, women were not allowed to enter the national air racing competition in 1934 due to sexism.

Thaden was a friend and rival of pioneer aviators Amelia Earhart, Pancho Barnes, Opal Kunz, and Blanche Noyes. Thaden defeated her colleagues in the first Women's Air Derby, also known as the Powder Puff Derby, in 1929. The Air Derby was a transcontinental race from Santa Monica, California to Cleveland, Ohio, which was the site of the National Air Races that year. It took place from August 13–20, 1929. Twenty women were entered in the race. Marvel Crosson was killed. Earhart damaged her aircraft at Yuma, Arizona, Barnes became lost and flew into Mexico and damaged her plane attempting to get back on course, and Noyes suffered an in-flight fire over Texas.

In 1930, Thaden went to work as the public relations director of Pittsburgh Aviation Industries (which had recently purchased her husband's Thaden Metal Aircraft Company) and became the director of the Women's Division of the Penn School of Aeronautics. That same year, Thaden and Earhart participated in the founding of an international organization for women pilots called the Ninety-Nines. Thaden turned down the presidency of the organization but served as the treasurer and vice-president. The Ninety-Nine organization still exists. In 1935, Phoebe Omlie, another pioneer female aviator, asked Thaden to become a field representative for the National Air Marking Program.
