Two British motoring pioneers whose names are forever linked by a hyphen made unlikely business partners.
Charles Stewart Rolls was born in 1877 in London's fashionable Mayfair district. As a member of the aristocracy, he was educated at one of the UK's top schools (Eton) and one of its best colleges (Trinity at Cambridge).
Frederick Henry Royce was born in 1863 near Peterborough, the son of a miller who died in poverty. Royce held a series of odd jobs -- including telegram messenger in Mayfair -- before an aunt sponsored his apprenticeship at the Great Northern Railway.
What the two men shared was a love for engineering and a passion for the car, an industry still in its infancy when they met in 1904.
They had separate roles. Royce was the practical, hard-working man who designed every element of Rolls-Royce engines and chassis. Rolls provided much of the finance -- and the social connections that generated sales.
It was a great partnership, but lasted only six years. In 1910, Rolls, an aviation pioneer, became the first Briton to die in an air crash. He was 32.
Royce continued to make all the company's engineering decisions, but was aided on the commercial side by Claude Johnson, a man many later called the hyphen in Rolls-Royce.
During World War I, Rolls-Royce began designing and manufacturing airplane engines, a business that was to become the dominant company activity.
