It is sometimes hard to reconcile that Jim Clark was 'a shy, unassuming sheep farmer from the Scottish borders' as well as the dominant racing driver of his day, feared by his rivals & lauded by many as the most natural racing driver of all time. He could drive all types of cars and won competitions in saloon cars, sports cars, touring cars and rally cars as well as Formula 1. He won the World Championship in 1963 & 1965. Andrew Tulloch writes this detailed biography with unique access provided by his position as curator of the Jim Clark Memorial Museum.
