A C Bertelli

Augustus Cesare Bertelli (1890–1979), known as "Bert" to his colleagues or "Gus" to his family, was an Anglo-Italian car designer, racing driver, mechanic, and businessman.

He returned to Italy and got a job in the development department of FIAT in Turin and while there met racing driver Felice Nazzaro and was taken on as a riding mechanic, winning the 1908 Targa Bologna.

Just before the outbreak of World War I he returned to the United Kingdom and studied aeronautical engineering and got a job in the design office of Grahame-White in Hendon, North London where he remained until 1918.

[1] He was then approached by Wallace Devereux of High Duty Alloys, a subsidiary of Hawker Siddeley, and asked to design a car but World War II broke out before a prototype was completed and work stopped.

Bill left the army aged 23 as an acting Major and embarked on a career in engineering in a variety of roles, Gus's brother Enrico (Harry) Bertelli was a coachbuilder who designed and made bodies for many pre-war Aston Martins in a factory next door to their works.
