Born in Coventry, the heart of the British motor industry, Brian Long comes from a family with a proud heritage in the automotive and aviation fields. He trained as a mechanical engineer, and worked for a time at his father's garage. Brian became heavily involved in the classic car scene at 19, and says he turned to writing by accident. He has a long association with several major car manufacturers, is a member of the Society of Automotive Historians, and a member of the Guild of Motoring Writers. He now writes full-time and, since 1990, when his first book was released, he has had more than 80 titles published. Brian currently lives with his family in Chiba, in Japan, where they enjoy life with their Dobermann and Thoroughbred racehorse.

Philippe Claverol is a French enthusiast, currently residing in Paris. As a Citroen executive, having been President of Citroen Japan and Citroen Czechoslovakia, Philippe naturally has strong links with the factory, but his love of the automobile spurred him on to undertake this project - his first book - in his spare time.
