William (Bill) Powell Lear (June 26, 1902 – May 14, 1978) was an American inventor and businessman. He is best known for founding the Lear Jet Corporation, a manufacturer of business jets. He also developed the 8-track cartridge, an audio tape system popular in the 1960s and 1970s. LifeLear was born in In the 1920s, Lear and a partner, Elmer Wavering, invented the first practical car radio, eventually selling their patents to the Galvin Corporation (which would later become the Motorola company). In 1930, Lear used his profits from the sale of his car radio patents to found Lear Developments, a company specializing in aerospace instruments and electronics. Lear developed radio direction finders, autopilots, and the first fully automatic aircraft landing system. His "LearAvian" series of portable radios, which incorporated radio direction finder circuits as well as broadcast band coverage, were especially popular. In 1941, Lear married his fourth wife Moya Marie Olsen, daughter of Vaudeville comedian John "Ole" Olsen. Lear changed the name of Lear Developments to Lear, Incorporated and in 1949 opened a manufacturing facility in In 1960, Lear moved to Lear died of leukemia on May 14, 1978. At the time of his death, Lear's current project was the Model 2100 Learfan, a seven-passenger plane whose tail mounted propeller was powered by two turboprop engines. Bill Lear and his wife, Moya, had four children: John, Shanda, David and Tina. InnovationsLear developed the Lear Jet Stereo 8-track music tape cartridge in 1964 as an improvement of the 4-Track Stereo-Pak tape cartridge (Fidelipak) marketed by Earl Muntz in The successful Canadair Regional Jet is largely based on Lear's design for the LearStar 600, which Canadair bought and turned into the Canadair CL-600 Challenger business jet. Lear Jet was acquired in 1990 by Bombardier Aerospace. One of Lear's most innovative projects was his last—a revolutionary airplane called the LearFan. The fuselage of this plane was made of lightweight composite materials instead of the standard aluminum material. It also featured an innovative "pusher" design, in which two aircraft engines powered a single spinning propeller blade that faced the rear of the aircraft. The LearFan, though many years in development, was ultimately never completed. He begged his wife, Moya Lear, to finish it, and with the help of investors, she attempted to do so. But the plane failed to obtain FAA certification, and never made it into production. This was not due to FAA concern about its use of innovative materials; rather, because of concerns that even with two engines, the gear mechanism that powered the single propeller might fail. If it did, the plane would crash. Copyright 2008 - France BtoB from Wikipédia
