[3] Moss became a successful London dentist, and from his mid-twenties he was also an enthusiastic competition driver, beginning his racing career at the Essex Motor Club's Winter Trial in 1921 driving a 1000 cc AV cyclecar.
His AV later caught fire in Park Lane, and Moss then acquired a GN cyclecar, with which he enjoyed success in trials and hillclimbs, and which he raced at Brooklands.
In 1922, he bought and began to race a Crouch Le Mans sports car which had no front brakes.
[5] In 1957 Moss and his son's manager Ken Gregory established the Formula One team British Racing Partnership with the objective to run cars for Stirling, when not under contract with other firms, along with other up-and-coming drivers.
[8] Moss died aged 75 in Stoke Mandeville, Aylesbury, Buckinghamshire,[1] on the 10th anniversary of his son being seriously injured in a car racing crash at Goodwood.
