The championship von Trips was leading when he was killed at Monza on 10 September, with one round remaining.
The season
Driving the Ferrari 156, von Trips won the Dutch Grand Prix at Zandvoort and the British Grand Prix at Aintree.
He arrived at Monza leading team-mate Phil Hill in the standings.
The accident
On the second lap, approaching the Parabolica, von Trips' Ferrari made contact with Jim Clark's Lotus.
The car went into an earth bank and along the spectator fencing before returning to the track. Von Trips was thrown out and killed. Fifteen spectators died.
The race continued
The grand prix was not stopped. Phil Hill won it and took the world championship, becoming the first American to do so.
Hill spoke afterwards about the impossibility of celebrating it.
The investigation
Italian prosecutors pursued a manslaughter case for several years. Clark and Ferrari were eventually cleared.
Consequences
The combined circuit incorporating the banked oval fell out of use for the Italian Grand Prix.
Germany did not have a Formula 1 world champion until Michael Schumacher in 1994.
The school
Von Trips had been establishing a karting facility for young German drivers. It continued after his death.
Why it goes on a wall
Because the championship of 1961 has a name on it and an absence beside it, and because a race that killed sixteen people was allowed to finish.
The crown left suspended.
