Rolls founded Rolls-Royce Ltd with Sir Frederick Henry Royce (1863-1933) in 1906, creating one of the world's most famous motoring companies. He was a keen motorist who competed in many early motor races, including the 1000 Mile Trial (1900), which he won. Also a keen aviator, Rolls was the first to make a non-stop double crosing of the English Channel by aeroplane.
