Educated at Sherborne, Dorset and then attended the Royal Military College. He joined the Royal Army Tank Corps in 1928, then in 1930 learned to fly with the Royal Air Force.
He raced Talbot and Lagonda cars; he won the Le Mans 24-Hour Race in 1935 in a 4½ litre Lagonda M45R Rapide with Luis Fontés (222 laps; 3006.797 km; average speed 125.283 km/h).
He was killed aged 30 while test flying Hawker Hurricane I L1652 at Brooklands on 6 September 1938; he is thought to have been overcome by carbon monoxide fumes in the cockpit, and the aeroplane then dived almost vertically into the ground and exploded at the foot of St George’s Hill almost opposite the Vickers factory entrance.
Hindmarsh married the multiple record breaking racing driver Violette Cordery on 15 September 1931 at Stoke D'Abernon parish church, and they had two daughters, one of whom married the racing driver Roy Salvadori.
