Bentley was founded by Walter Owen Bentley, known to all as "W.O." He was a born engineer, but his first experience was not with motor cars - it was trains. In 1905, aged 16, he set off on his bicycle to work at the Great Northern Railway Locomotive Works in Doncaster, northern England.
Off duty, he soon abandoned the push-bike in favour of motor cycling and with his brother took to racing. In their first event, the London to Edinburgh Trial, they won a gold medal. W.O. raced at the Isle of Man TT event and Brooklands race track, near London.
The internal combustion engine made sweeter music to his ears than steam trains and in 1912 Bentley's family found funds enough to buy a small company importing French DFP sports cars.
It was on a visit to the DFP factory in 1913 that W.O. noticed an aluminium paperweight - and had the inspired idea of using the lightweight metal instead of cast iron to make engine pistons. The first such Bentley pistons went into service in aero engines for the Sopwith Camel, in service during the Great War.
After it, Bentley revived his motor car interests and in London set about development of a racing engine - Experimental Bentley No 1. "I wanted to make a fast car, a good car: the best in its class..."
And he did. In the '20s, with the 3-litre, 85bhp engine providing speeds of 80 mph and more, Bentley Motors set numerous speed and endurance records, competed successfully at Indianapolis, the Isle of Man, and Brooklands - and became inextricably linked with the history of the famous 24 hour race at Le Mans. In the hands of the legendary Bentley Boys, Bentleys achieved Le Mans victories in 1924, 1927, 1928, 1929, and 1930 - taking first four places in 1929.
Yet despite its racing record and public acclaim, Bentley Motors was beset by financial difficulty. By 1931 the golden age was over, but as closure loomed, Rolls-Royce stepped in to save the Bentley name - and a new era began.
