Alexander Mathieson started as a plane maker in 1822 in Saracen Lane Glasgow Scotland. In 1854 his son Thomas joined him and the company changed its name to A. Mathieson & Son Saracen Tool Works. Thomas lifted the company and made it the most prolific British planemaker of all time. Around 1955 they became a part of the Record Company.
