Donald Healey was born on 3rd July 1898 in Perranporth, Cornwall, elder son of Frederick (John Frederick) and Emma Healey (née Mitchell) who at that time ran a general store there.
Donald became interested in all things mechanical at an early age, most particularly aircraft. He studied engineering while at Newquay College.
When he left his father bought him an expensive apprenticeship with Sopwith Aviation Company in Kingston upon Thames, Surrey and he joined Sopwith in 1914 continuing his engineering studies at Kingston Technical College.
Sopwith had sheds at the nearby Brooklands aerodrome and racing circuit.
Barely 16 when WW1 started, he volunteered in 1916 (before the end of his apprenticeship) for the Royal Flying Corps (RFC) and earned his "wings" as a pilot. He went on night bombing raids and served on anti-Zeppelin patrols and also as a flying instructor.
Shot down by British anti-aircraft fire on one of the first night bomber missions of the war, after a further series of crashes he was invalided out of the RFC in November 1917 and spent the rest of the war checking aircraft components for the Air Ministry.
After the Armistice he returned to Cornwall, took a correspondence course in automobile engineering and opened the first garage in Perranporth in 1920.
Healey found rally driving and motor racing more interesting than his garage and its car hire business and used the garage to prepare cars for competition.
