The margin, in points, by which Hawthorn won the 1958 world championship from Stirling Moss: 42 to 41.
He won one grand prix that year. Moss won four.
The bow tie
Hawthorn habitually raced wearing a bow tie, part of a deliberately amateur, pre-war presentation that was already out of date in the late 1950s.
Porto, 1958
At the Portuguese Grand Prix Hawthorn faced disqualification for restarting his car against the direction of travel.
Stirling Moss, his championship rival, told the stewards that Hawthorn had been off the track when he did it, and the penalty was dropped.
The six points retained decided the championship in Hawthorn's favour.
Le Mans, 1955
Hawthorn won the 1955 Le Mans 24 Hours, the race in which Pierre Levegh's Mercedes went into the crowd, killing more than eighty spectators.
Hawthorn's braking to enter the pits was part of the chain of events. The official inquiry did not find him at fault. The association followed him for the rest of his life.
Collins
Peter Collins, Hawthorn's Ferrari team-mate and closest friend, was killed at the Nurburgring on 3 August 1958.
Hawthorn's own account of the remainder of the season is that the championship had lost most of its meaning.
Retirement and death
Hawthorn announced his retirement shortly after securing the title, at twenty-nine.
On 22 January 1959 he was killed when his Jaguar left the Guildford bypass in wet conditions and struck a tree.
Why it goes on a wall
Because the man who gave up the championship to keep it honest was Moss, the man who won it walked away from the sport three months later, and the road killed him instead of the circuit.
Champion by one point.
