Mary Anita "Neta" Snook Southern was a pioneer aviator who achieved a long list of firsts. She was the first woman aviator in Iowa, first woman student accepted at the Curtiss Flying School in Virginia, first woman aviator to run her own aviation business and first woman to run a commercial airfield. Yet "Snooky", as her friends called her, was fated to be remembered for her relationship to Amelia Earhart. Her autobiography I Taught Amelia to Fly captures the essence of her fame and she is linked to Earhart, as her first instructor.

Winfield Bertrum "Bert" Kinner was an American aircraft engine designer and designer of the first folding wing aircraft. Kinner founded Kinner Airplane & Motor Corporation in Glendale, California, which produced radial engines and aircraft.
