D'Arcy Richard Baker (1877-1932) was a British businessman and racing driver. Baker was managing director of Fiat in the UK. In the early 1900s he extensively renovated Hedsor House, a mansion he owned in Hedsor, Buckinghamshire, but the expense led to his bankruptcy, and on his death his estate passed to his bankers, and then to the Shepherd family in 1934. In 1908, at Brooklands, Frank Newton drove a 90hp Napier motor car for its Australian owner Selwyn Edge, who had a £500 bet with Baker that his car could go faster than Felice Nazzaro's Fiat, but the Napier suffered from mechanical trouble.
