Jack Rex Lewis (1 November 1936 - Present): British racing driver from Stroud, Gloucestershire, the son of a motorcycle dealer who ran H&L Motors. His racing career began in Formula Three in 1958 when he bought a Cooper-Norton from Cheltenham-based Ivor Bueb, remarkably finishing fourth on his debut at Mallory Park. In his first season he raced 13 times, winning three races and finishing on the podium four more times. In 1959 driving a Formula Two Cooper-Climax he won his first F2 race at Paris Montlhéry by over two minutes.
The following year Lewis won the F2 championship ahead of World Champion Jack Brabham. He moved to Formula One for 1961, purchasing a Cooper T53 Climax, and made his Grand Prix debut in Belgium in June finishing ninth. He achieved an excellent career-best fourth place at the Italian GP at Monza, holding off Tony Brooks' late challenge. He bought a 1961/62 BRM V8 to race but the car was unsatisfactory and eventually went back to the factory, forcing him to return to his Cooper, though he achieved seventh place at the Dutch Grand Prix.
He participated in 10 Formula One World Championship Grands Prix, scoring three championship points total. By 1963, feeling despondent, Lewis retired from racing at age 27 and took on a farm in Llandovery, Carmarthenshire where he bred Arab horses and raised two daughters.
