The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American aviation pioneers generally credited[1][2][3] with inventing, building, and flying the world’s first successful airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, four miles south of Kitty Hawk, North Carolina.

Childhood
The Wright brothers were two of seven children born to Milton Wright (1828–1917), of English and Dutch ancestry, and Susan Catherine Koerner (1831–1889), of German and Swiss ancestry.[16][17]

The other Wright siblings were Reuchlin (1861–1920), Lorin (1862–1939), Katharine (1874–1929), and twins Otis and Ida (born 1870, died in infancy).
