The year Tom Simpson died on Mont Ventoux during the thirteenth stage of the Tour de France, on 13 July.
The career
Simpson moved to France in 1959. He became the first British rider to wear the yellow jersey, in 1962, and finished sixth overall that year.
He won the Tour of Flanders in 1961, Milan to San Remo in 1964, Bordeaux to Paris and the Giro di Lombardia in 1965, and Paris to Nice in 1967.
He was world road race champion in 1965 and BBC Sports Personality of the Year the same season.
The image
He cultivated an English gentleman persona for the continental press, including photographs with bowler hat and umbrella, and was widely popular in France and Belgium.
Ventoux
The stage crossed Mont Ventoux in extreme heat. Simpson, thirteenth on general classification, attacked with the leaders.
About a mile from the summit he began weaving and fell. Spectators remounted him at his request. He rode a short distance further, collapsed again, and could not be revived.
The autopsy
Amphetamines were found in his body and in his jersey pockets. Dehydration, extreme heat and alcohol consumed during the stage were also cited.
The Tour introduced drug testing the following year.
The memorial
A granite memorial was erected near the place he fell, funded partly by British cyclists.
Riders climbing the mountain routinely leave bidons, caps and other items at it.
Why it goes on a wall
Because it is not a cautionary tale with a villain. It is a rider doing what the sport of his time quietly expected, on a mountain that punishes exactly that, in front of everyone.
The Ventoux keeps him.
