[1] He began his football career at his hometown club US Boulogne, whose pitch, called the Moulin Wibert, was perched on top of a cliff, thus being both steep and exposed to all the winds.
[1] On 1 November 1906, probably because of his size, Bon was pre-selected for his first international match for France, a friendly against England amateurs, with the following comment: "Completely unknown in Paris, he is considered one of the best forwards in the North".
[3][4][1] During the match, he co-scored the winning goal (2–1), which was described in the press as follows: "Puget crosses the ball into the area where; at the same time, François, Bon, and Camard push the Belgian goalkeeper Robert Hustin together, and the four men roll into the net".
[1] After this match, France's captain Fernand Canelle congratulated Bon, stating that he was "an example to French forwards; he knew how to mark his opponent the moment they received the ball, and this saved his half-backs and full-backs unnecessary work"; in other words, Bon was the first French forward to carry out defensive work in international matches, doing so spontaneously (because there was no coach at the time).
[1] Despite Canelle's compliment, Bon never became unanimous, and likewise, he was not selected in any of the next three Paris-Nord meetings between 1908 and 1910, but when he finally got another chance in 1911, he delivered two assists in a 3–1 win.
