Before the war Gaudermen played rugby, appearing for the club "Stade Français" when they became champions in 1903 and finalists in 1904, and later for "Racing Club de France". He was capped once for France in a game against England at "Parc des Princes", Paris, on 22 March 1906. Gaudermen also took part in the 1907 French Grand Prix as riding mechanic to Albert Clément. On 17 May, during a practice lap, their car overshot a bend and hit a pile of sand near Saint-Martin-en-Campagne. Gaudermen was thrown clear, suffering only minor injuries, but Clément stayed with the car as it rolled several times, and broke his neck killing him instantly.
