John Young Sangster was a British industrialist and philanthropist. He was an important figure in the British motorcycle industry, where he was involved with Ariel, BSA and Triumph.

The Rover 8 was a small single-cylinder 8 hp 1327 cc car made by the British Rover car company. It was Rover's first production car. It was remarkable for being supported by a backbone chassis rather than a conventional ladder frame. The first model was manufactured from 1904 to 1912. A Daimler-Knight sleeve valve engine option was available on the original model in 1911 and 1912.
