Allison History1920 - 1929
With successes such as the development of the steel-backed bronze sleeve bearings, a key component in the famed Liberty aircraft engine, Allison Engineering Company had become a major player in engine development by the late 1920s. Throughout the 1920s, the company achieved a range of innovative breakthroughs, including high-speed reduction gearing for aircraft motors and propellers and Roots-type blowers to boost engine manifold pressure.
In 1928 Jim Allison died, and Allison Engineering Company was put up for sale. General Motors purchased the company in 1929.
