Emeryson was a Formula One constructor briefly in , and then again briefly in and .
The company was named for Paul Emery, whose father George had built specials before the war; in 1948, one of the specials was extended to take a 4 litre Duesenberg engine for the Northern Irish racer Bobbie Baird, and entered for the 1948 British Grand Prix, but various issues prevented the car from starting.
In 1949, George and his brother Peter built a 500cc formula racing car, which Paul raced. The company continued building cars to the formula for much of the 1950s, while Paul himself built an Alta-engined Formula 2 car in 1953, followed by an Aston Martin-engined special which qualified for the new Formula 1 in 1954.
The car made its Formula 1 debut in the hands of Colin Chapman at the 1954 BRDC International Trophy, but, proving slow and unreliable, finished 17th and last, so Emery replaced the engine with an Alta engine bored out to 2.5 litres. In this configuration, the car proved much more of a prospect, Emery finishing second in the London Trophy at Crystal Palace in 1956 after dicing for the win with Stirling Moss' Maserati 250F, and Emery made his sole world championship start in the 1956 British Grand Prix, albeit retiring early with an ignition problem after running last.
In 1960, Emery teamed up with Alan Brown and planned a run of 50 two-litre racing cars. The outcome was a run of Formula Junior cars and a new Formula 1 model, with a Coventry Climax engine; the Ecurie Nationale Belge team bought three cars, fitting two with Maserati engines, and one of the latter recorded a 4th place in the 1961 Brussels Grand Prix with Lucien Bianchi driving.
During the year, American heir Hugh Powell bought the company with a view to running Tony Settember in the car. Settember was joined by John Campbell-Jones in 1962 and by the end of the year the cars had been modified into the new Scirocco marque.
