Who were the Wright brothers?
The Wright brothers — Wilbur (1867–1912) and Orville (1871–1948) — were American bicycle makers who achieved the first sustained, controlled, powered heavier-than-air flight on December 17, 1903, at Kitty Hawk, North Carolina: Orville's first hop lasted 12 seconds and covered 120 feet.

Where rivals chased raw engine power, the brothers solved the real problem — control. Their three-axis system of wing-warping, forward elevator and rear rudder let a pilot steer in the air, and it remains the basis of how every airplane flies today.
Wilbur Wright (1867-1912) and Orville Wright (1871-1948) were two of seven children of Milton Wright, a bishop in the Church of the United Brethren in Christ, and Susan Catherine Koerner Wright, who had attended college and was mechanically skilled. The family lived in Dayton, Ohio, where the brothers ran a printing business and then, from 1892, a bicycle shop. The bicycle business mattered more than it might seem: building and repairing bicycles taught them about lightweight structures, chain drives, bearings, and balance, and it gave them the income and the workshop they would use to build flying machines. They were not wealthy, and they had no university degrees. What they had was a workshop, a habit of careful experiment, and each other.
The brothers were close collaborators who worked as a team and patented their inventions jointly. Wilbur, the elder, was the more reflective and theoretical of the two; Orville was the more mechanical. They argued constantly, tested everything, and kept meticulous records. That discipline set them apart from many of their rivals in the race to fly, who were often better funded and better connected but less systematic. The Wrights approached flight as an engineering problem to be solved piece by piece: first lift, then control, then power, in that order.
Their interest in flight began in the 1890s, stirred by the death of the German gliding pioneer Otto Lilienthal in a glider crash in 1896 and by the writings of the French-born experimenter Octave Chanute. They read everything they could find on the subject, including the work of the American engineer and Smithsonian secretary Samuel Pierpont Langley. In 1899, Wilbur wrote to the Smithsonian Institution asking for papers on flight. The Institution sent him what it had, and the brothers began a program of study that would take them from kites to gliders to powered flight in four years.
Most would-be aviators of the era believed the main obstacle to flight was power: build an engine strong enough, and the airplane would follow. The Wrights reached a different conclusion. They studied birds and noticed that birds steer by twisting their wings and changing their angle to the air. From this they developed the idea of wing-warping: cables that twisted the wings of a glider so that one wingtip rose and the other fell, allowing the pilot to bank and turn. A forward elevator controlled pitch, the nose-up or nose-down attitude, and a rear rudder controlled yaw, the sideways swing of the nose. Together, the three controls gave the pilot command of the airplane in three axes. That three-axis system remains the basis of how airplanes are controlled today.
The brothers tested their ideas at Kitty Hawk, on the Outer Banks of North Carolina, chosen for its steady winds, soft sandy landing ground, and relative privacy. They began with kites and gliders. Their 1900 and 1901 gliders disappointed them: they produced less lift than the published tables of the time predicted. Rather than blame their craftsmanship, the Wrights questioned the tables. In the winter of 1901-02, back in Dayton, they built a wind tunnel, a wooden box with a fan, and tested more than two hundred model wing shapes, measuring lift and drag with balances of their own design. The data corrected the old tables and let them design a glider that actually worked. The 1902 glider made hundreds of successful glides, some lasting half a minute, and proved that three-axis control worked in the air. The brothers later called the 1902 glider their most important machine, because it solved control before they ever added an engine.
Power came last. The brothers needed an engine light enough to fly and strong enough to pull their airframe. No manufacturer would build one to their specifications, so their bicycle-shop mechanic, Charlie Taylor, built a twelve-horsepower gasoline engine in six weeks. The brothers designed the propellers themselves, treating them as rotating wings rather than as screws through the air, an insight that made their propellers far more efficient than those of their rivals.
On the morning of December 17, 1903, at Kill Devil Hills near Kitty Hawk, the Wrights' powered machine, the Flyer I, made history. The airplane had a wingspan of about twelve meters, a wooden frame covered in fabric, and a chain-driven pair of propellers pushed by the Taylor engine. The brothers tossed a coin for the first flight; Wilbur won and made an unsuccessful attempt on December 14. On December 17, it was Orville's turn. At 10:35 in the morning, the Flyer lifted off its launch rail, stayed airborne for twelve seconds, and traveled about 120 feet. It was, in the brothers' own terms, the first sustained, controlled, powered flight of a heavier-than-air machine with a pilot aboard. The word controlled matters: earlier machines had made powered hops, but the Wright Flyer could be steered in the air and landed at a spot the pilot chose.
The brothers made four flights that day. The fourth, piloted by Wilbur, lasted fifty-nine seconds and covered about 852 feet. Then a gust of wind flipped the Flyer and damaged it beyond quick repair. The brothers sent a telegram to their father in Dayton announcing the flights, and that evening they took the train home. A local newspaper had been told of the flights, but the story was widely disbelieved or ignored: the first accounts were garbled, and the claim seemed too large to credit. It took years of public demonstrations before the world accepted what had happened on a cold beach in North Carolina.
The Flyer I never flew again. The brothers went on to build better machines at Huffman Prairie, a pasture outside Dayton, where in 1904 and 1905 they flew the Flyer II and Flyer III. In October 1905, the Flyer III stayed aloft for thirty-nine minutes and covered about twenty-four miles, circling the field again and again. The brothers considered that machine the first practical airplane: it could take off, fly a sustained course, and return to land. But they kept their work secret while they sought patents and contracts, and for two years the world heard little from them. Skeptics, particularly in Europe, began to call them bluffers. The brothers would answer in public, and decisively, in 1908.
In 1908, the Wrights split up to demonstrate their machine on two continents. Wilbur went to France, where at Le Mans in August he flew before crowds that included reporters, officials, and rival aviators. His flights, graceful figure-eights and long sustained turns, stunned the European aviation community, which had believed powered flight to be at a far more primitive stage. Orville went to Fort Myer, Virginia, to demonstrate a machine for the United States Army. There, in September 1908, a crash killed his passenger, Lieutenant Thomas Selfridge, and badly injured Orville. Selfridge became the first person to die in a powered airplane crash, and the first fatality of American military aviation.
The brothers' success brought fame, fortune, and a decade of litigation. In 1909, they won a contract to sell a military flyer to the United States Army Signal Corps, and they formed the Wright Company to manufacture airplanes. But their patent on three-axis control, granted in 1906, became the center of a long patent war, above all with the American aviator Glenn Curtiss. The legal battles consumed the brothers' time and energy and slowed the development of American aviation, a cost that historians still debate. Wilbur died of typhoid fever in 1912, at forty-five, exhausted by the lawsuits. Orville sold the company in 1915 and spent his later years as an elder statesman of aviation.
One dispute followed Orville for decades. The Smithsonian Institution had backed Langley's Aerodrome, a machine that failed to fly in 1903; years later, the Smithsonian displayed a rebuilt Aerodrome as capable of flight, and Orville, in protest, sent the original 1903 Flyer to the Science Museum in London in 1928. The Flyer returned to the United States only after Orville's death, and it now hangs in the National Air and Space Museum in Washington. The brothers' achievement is commemorated at the Wright Brothers National Memorial at Kill Devil Hills, where a granite pylon stands on the dune from which they flew. Their true monument is larger: every airplane in the sky today is still steered by the three-axis system they worked out in a bicycle shop in Dayton.
