Katharine Wright Haskell was an American teacher, suffragist, and the younger sister of aviation pioneers Wilbur and Orville Wright. She worked closely with her brothers, managing their bicycle shop in Dayton, Ohio, when they were away; acting as their right-hand woman and general factotum in Europe; assisting with their voluminous correspondence and business affairs; and providing a sounding board for their far-ranging ideas. She pursued a professional career as a high school teacher in Dayton, at a time when few middle-class American women worked outside the home, and went on to become an international celebrity in her own right. A significant figure in the early-twentieth-century women's movement, she worked actively on behalf of woman suffrage in Ohio and served as the third female trustee of Oberlin College.

The Wright brothers, Orville Wright and Wilbur Wright, were American aviation pioneers generally credited with inventing, building, and flying the world's first successful airplane. They made the first controlled, sustained flight of an engine-powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, four miles (6 km) south of Kitty Hawk, North Carolina, at what is now known as Kill Devil Hills. In 1904 the Wright brothers developed the Wright Flyer II, which made longer-duration flights including the first circle, followed in 1905 by the first truly practical fixed-wing aircraft, the Wright Flyer III.
