Eloi Meulenberg was a member of an outstanding group of Belgian cyclists in the 1930s. He played a key role in supporting Sylvère Maes' successful (and unsuccessful) Tour de France campaigns, by winning a total of nine stages across the 1936, 1937 and 1938 Tours.
Eloi was also World Road Race Champion in 1937 (using a Super Champion derailleur). His Belgian team mates, Karel Kaers, Jean Aerts and Marcel Kint won the World Road Race Championships in 1934, 1935 and 1938 respectively. They were a powerful crew.
This excellent photo shows a gentleman who looks curiously like David Cameron giving bottles of Perrier water to Eloi Meulenberg after Eloi's victory in stage 6 of the 1936 Tour de France. It is one of three images of Eloi Meulenberg on this site, the others are here and here.
