Wright Brothers

In 1892, the brothers opened a bicycle sales and repair shop, and they began to build bicycles on a small scale in 1896. They developed their own self-oiling bicycle wheel hub and installed a number of light machine tools in the shop. Profits from the print shop and the bicycle operation were eventually to fund the Wright brothers' aeronautical experiments from 1899 to 1905. In addition, the experience of designing and building lightweight, precision machines of wood, wire, and metal tubing was ideal preparation for the construction of flying machines. In later years, the Wrights dated their fascination with flight to a small helicopter toy that their father had brought home from his travels when the family was living in Iowa. A decade later, they had read accounts of the work of the German glider pioneer Otto Lilienthal. But it was news reports of Lilienthal's death in a glider crash in August 1896 that marked the beginning of their serious interest in flight. By 1899, the brothers had exhausted the resources of the local library and had written to the Smithsonian Institution for suggestions as to further reading in aeronautics. The following year they wrote to introduce themselves to Octave Chanute, a leading civil engineer and an authority on aviation who would remain a confidant of the brothers during the critical years from 1900 to 1905.
