Anquetil was the son of a builder in Mont-Saint-Aignan, in the hills above Rouen in Normandy, north-west France. He lived there with his parents, Ernest and Marie, and his brother Philippe and then at Boisguillaume in a two-storey house, "one of those houses with exposed beams that tourists think are pretty but those who live there find uncomfortable." In 1941, his father refused contracts to work on military installations for the German occupiers and his work dried up. Other members of the family worked in strawberry farming and Anquetil's father followed them, moving to the hamlet of Bourguet, near Quincampoix.

Anquetil unfailingly beat Raymond Poulidor in the Tour de France and yet Poulidor remained the more popular. Divisions between their fans became marked, which two sociologists studying the impact of the Tour on French society say became emblematic of France old and new.  The extent of those divisions is shown in a story, perhaps apocryphal, told by Pierre Chany, who was close to Anquetil:  The Tour de France has the major fault of dividing the country, right down to the smallest hamlet, even families, into two rival camps. I know a man who grabbed his wife and held her on the grill of a heated stove, seated and with her skirts held up, for favouring Jacques Anquetil when he preferred Raymond Poulidor. The following year, the woman became a Poulidor-iste. But it was too late. The husband had switched his allegiance to Gimondi. The last I heard they were digging in their heels and the neighbours were complaining.  Jean-Luc Boeuf and Yves Leonard, in their study, wrote:  Those who recognised themselves in Jacques Anquetil liked his priority of style and elegance in the way he rode. Behind this fluidity and the appearance of ease was the image of France winning and those who took risks identified with him. Humble people saw themselves in Raymond Poulidor, whose face - lined with effort - represented the life they led on land they worked without rest or respite. His declarations, full of good sense, delighted the crowds: a race, even a difficult one, lasts less time than a day bringing in the harvest. A big part of the public therefore finished by identifying with the one who symbolised bad luck and the eternal position of runner-up, an image that was far from true for Poulidor, whose record was particularly rich. Even today, the expression of the eternal second and of a Poulidor Complex is associated with a hard life, as an article by Jacques Marseille showed in Le Figaro when it was headlined "This country is suffering from a Poulidor Complex".Answer this question using a quote from the following article:
