Hawthorn's death early in 1959 compounded a tragic season for Formula One, with four drivers killed or fatally injured on the track. Luigi Musso died in the French Grand Prix, Peter Collins a month later in the German Grand Prix – just two weeks after winning his home race, Lewis-Evans died in hospital following his fire in Morocco and Pat O'Connor died at the Indianapolis 500 (which, at the time, was a round of the World Championship).
