His nom de guerre was Clement, hence the "dit Clement" on the memorial to him in Grenoble. He was also a decorated war hero of the First World War. Eugène Chavant was born on the 12th of February 1894, at Colombe, Isère, the son of a shoe-maker.
He was a student at the village school before becoming a mechanic in a factory, during which time he followed the distance-learning programme of the Ecole du Génie Civil which allowed him to become a master tradesman.
In 1914, he was mobilised in the 11th Dragoons, then transferred to the 20th Battalion of Chasseurs where he was made a sergeant and platoon leader. Gassed near Soissons in 1918, he refused to leave the front.
In Grenoble, he is commemorated by the tram-stop (lines A and C) Chavant.
