[1] Beltette attended primary school in his native village, run by the teacher Evariste Harduin, to whom he was very grateful for his teaching and who encouraged him to undertake secondary studies at the college of Saint-Riquier (Somme).
[1] Despite failing the competitive examination four times, Beltette still managed to acquire in the city, as in high school, a "very legitimate consideration" according to the inspector general in 1908.
[1] During an internship across the English Channel, Beltette developed a deep interest in the sport of football, and he went on to become one of the pioneers of its diffusion in northern France.
[1][6] Therefore, Beltette introduced the sport of football to several of his students, many of which would later become French internationals, such as Adrien Filez (5),[5] Fernand Desrousseaux (1),[7] Gabriel Hanot (12), Jules Dubly (1), and Henri Moigneu (8).
[1] After the war, he was Secretary General of the BIES from 1920 to 1931; before the 1926 congress held in Geneva, Beltette and Jean Clavière, who had been his colleague in Dunkirk, expressed their objectives to the press: "The work of peace, as the League of Nations is trying to achieve it, will encounter constantly renewed difficulties, as long as the educators of those who will be the intellectual elite of the nations, that is to say, the secondary school teachers, have not modified the state of mind of the peoples and created in the world the new spirit that present-day humanity demands".
