Philip Porter has written about 30 motoring books, twice winning the Montagu Trophy for best motoring book of the year. A lifelong motor racing enthusiast, that enthusiasm was largely fired by Stirling Moss. Like so many young boys in the fifties, he was Philip’s absolute hero. As a consequence, Philip began successfully competing in motor sport while still at school. He began acquiring classic sports cars long before it became a boom and owns 9600 HP, the oldest E-type in existence. This led to some motoring journalism among his busy business career. He later satisfied his competitive spirit with flying hot air balloons and airships, winning the silver medal at the 1991 European Airship Championships. In 1992 he became the first person ever to fly an airship in Africa. He is Chairman of the Sherlock Holmes Society and an active member of the Jerome K. Jerome Society. In 1997 he and his wife Julie founded the International Jaguar XK Club and in 2004 they started the Jaguar E-type Club. Philip edits both monthly magazines and Sir Stirling is Patron of the XK Club. Philip and Julie live in a Tudor farmhouse in Worcestershire and have their offices in an adjoining thatched barn.
