Inventor of the Lear Jet Remembering Bill Lear

William Powell "Bill" 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 invented the battery eliminator for the B battery, and developed the 8-track cartridge, an audio tape system.[1] Throughout his career of 46 years, Lear received over 120 patents. Lear developed the Lear Jet Stereo 8 music cartridge in 1964, better-known as the "8-track". This was an eight track variation of the four track Muntz Stereo-Pak tape cartridge, marketed by Earl "Madman" Muntz in California in 1962, itself a version of a 3-track system, Fidelipac. The 8-track was a commercial success that provided good audio quality and was easily adapted to vehicle and home use.[4] It was a solution to the need for a convenient music source for his new business jets. The consumer version of players for these tapes first appeared in September 1965 in 1966 model Ford automobiles with RCA and Lear offering the first pre-recorded Stereo 8 Music Cartridges. In 1968, Lear also started work on a closed circuit steam turbine to power cars and buses, and built a transit bus and converted a Chevrolet Monte Carlo sedan to use this turbine system. It used a proprietary working fluid dubbed Learium, possibly a chlorofluorocarbon similar to DuPont Freon.[5] In 1969, Lear and his friend Art Linkletter offered their support for Craig Breedlove's supersonic car project. Lear founded Lear Developments, a company specializing in aerospace instruments and electronics.[6] Lear developed radio direction finders, autopilots, and the first fully automatic aircraft landing system. He was awarded the Collier Trophy for this contribution in 1949. He's most remembered for his line of business jets starting with the Learjet 23, the first mass-produced business jet. PJ 159
