Lycoming traces its beginning to a mid-nineteenth century sewing machine manufacturer. Sold and restructured in 1907 as the Lycoming Foundry and Machine Company, it produced automobile engines, and later was a subsidiary of the Auburn Auto Company. Although its early aircraft engines were radials, Lycoming entered the light-aircraft engine field early in 1938 with the introduction of the air-cooled, four-cylinder, horizontally opposed O-145 engine.

Along with Continental and Franklin, Lycoming was a basic provider of engines for the ubiquitous bright yellow Piper Cub, which sold for less than $2,000, and synonymous with small general aviation aircraft for many years. Appearing in 1939, the O-145-B2 powered such aircraft as the Piper J3L-65, Taylorcraft BL-12-65, and Mooney M-18 Mite. Manufactured until 1950, the later C-model of the O-145 produced 56 kW (75 hp).

Most recently Lycoming became a subsidiary of Textron Inc.
