Sunbeam Aircraft and Aero Engines
Louis Coatalen joined Sunbeam as chief engineer in 1909. He was previously chief engineer at the Humber works in Coventry and had gained a lot of experience in the industry. Until now Sunbeam had brought-in many of their parts, but under Coatalen most were now made in Wolverhampton.

His slogan was 'Racing improves the breed'.
