Louis "Louison" Bobet (pronounced [lwi.zo bo.be]; 12 March 1925 - 13 March 1983) was a French professional road racing cyclist. He was the first great French rider of the post-war period and the first rider to win the Tour de France in three successive years, from 1953 to 1955. His career included the national road championship (1950 and 1951), Milan-San Remo (1951), Giro di Lombardia (1951), Criterium International (1951 & 52), Paris-Nice (1952), Grand Prix des Nations (1952), world road championship (1954), Tour of Flanders (1955), Criterium du Dauphine Libere (1955), Tour de Luxembourg (1955), Paris-Roubaix (1956) and Bordeaux-Paris (1959).

The most striking feature of Bobet the man rather than rider was his ambition to behave like a Hollywood matinee idol, a sort of David Niven character in a dinner suit tuxedo. It brought him much ribbing from other French riders. Geminiani says Bobet's diffident and elegant manner made him less popular even in his own Brittany than the more rustic, forthright manners of other Breton people such as Jean Robic. The British professional Brian Robinson called Bobet "a private man and a little moody" and said he would sulk if things went wrong. The French journalist Rene de Latour said of Bobet in Sporting Cyclist that "he didn't look good on a bike" and that he had "the legs of a football [soccer] player".  Bobet spoke out against French involvement in a war against communists in Indo-China. He said he wasn't a Marxist but a pacifist. Geminiani said Bobet lacked humility. "He really thought that, after him, there'd be no more cycling in France", he said. Bobet occasionally talked of himself in the third person.  Bobet was driven by personal hygiene and refused to accept his first yellow jersey because it had not been made with the pure wool he believed the only healthy material for a sweating and dusty rider. Synthetic thread or blends were added in 1947 following the arrival of Sofil as a sponsor. Sofil made artificial yarn. The race organiser, Jacques Goddet wrote:  It produced a real drama. Our contract with Sofil was crumbling away. If the news had got out, the commercial effect would have been disastrous for the manufacturer. I remember debating it with him a good part of the night. Louison was always exquisitely courteous but his principles were as hard as the granite blocks of his native Brittany coast.  Goddet had to get Sofil to produce another jersey overnight, its logo still visible but artificial fabric absent. Bobet's concern with hygiene and clothing was accentuated by frequent problems with saddle sores. Answer this question using a quote from the following article:
