　　The Wright Brothers

　　Aviation pioneers, inventors. Wilbur was born near Millville, Indiana, and Orville was born in Dayton, Ohio. The sons of a minister of the United Brethren Church, the Wright brothers showed mechanical genius from boyhood, although neither graduated from high school.

　　In 1892 they opened a bicycle sales and repair shop in Dayton and soon were making and selling their own bicycles. Reading about experiments with gliders spurred their interest in flight, and they built their first glider in 1899, a biplane kite with wings that could be twisted mechanically.

　　The brothers made their first trip to Kitty Hawk, North Carolina in 1900 to conduct glider experiments on the sand hills there.

　　Back in Dayton they built the first wind tunnel and prepared their own tables of lift-pressures for various wing surfaces and wind speeds. They also built a powerful four-cylinder engine and an efficient propeller, and in September 1903 they returned to Kitty Hawk. Bad weather delayed the testing of this aircraft until December 17, 1903, when Orville piloted it on a flight of 12 seconds and 120 feet; Wilbur flew later in the day, staying aloft for 59 seconds to cover 852 feet.
