John (Jack) Nicholson was born in September 1914 in Penrith, Cornwall. As teenager he went to work for the Co-Op, for which he eventually became a travelling salesman. In 1937, Jack Nicholson married Joan Davidson, whose family owned Davidson’s Garage, which Jack would eventually take over. During World War II he served in the RAF at Turnhill and then in India and Burma until the end of the war and returned to the Co-Op as a mechanic, maintaining the firm’s delivery vans. When Jack's father-in-law fell ill, he went to work at the family garage and developed his interest in motor racing and purchased a Cooper-Norton 500cc, the first racing car in Penrith.
Some results for Jack:
As a novice part-time enthusiast, he had some successes at hill climbs and on the track. His real success came when driving his home-built car, a 3.4 litre ERA/Jaguar in which he won the race for unlimited sports cars at Aintree Circuit Club’s meeting at Liverpool.
