When Jackie Stewart was starting out in motor sports he was initially known as "Jimmy Stewart's younger brother", although it did not take long for him to make a name in his own right. Jimmy Stewart started off on hillclimbs before signing for the Ecurie Ecosse team where he drove Jaguar C-types. From there he moved on to Formula 2 and eventually into Formula One in a Cooper-Bristol.

He made his championship F1 debut at Silverstone in 1953, making an immediate impression with a solid drive which saw him climb through the field before he spun off while lying sixth with 11 laps to go. Although it was assumed that was just the start, it was to be his only F1 championship outing. In 1954 he crashed at Le Mans, badly injuring an arm, and he inflicted further damage to the same arm when he had an accident at the Nurburgring a year later, prompting his retirement.

He moved to America but suffered from alcoholism which he eventually overcame with help from his brother, who he remained very close to. Jackie Stewart wrote that he owed his older brother almost everything. "I found my real salvation in motor racing, and I found it because, in my difficult time of need and confusion, it was my elder brother who carried the torch and selflessly showed me the way."
