He co-founded the 'Société des humoristes' in 1907, joined the Société Nationale des Beaux-Arts in 1910, and was named a Knight in the Legion of Honor the next year. He also designed decorations for public festivities, including floats for the satirical Vachalcades and the Cabaret des Quat'z'Arts.
During World War I, he volunteered as a lieutenant in the engineering regiment and assisted Guirand de Scevola in organizing the Camouflage Division's central workshop, while continuing to draw caricatures for Le Petit Journal. He died from wounds in a military hospital at Auxerre shortly before the war's end.
After his death, his widow, the painter Julia Abel-Truchet, took over his Montmartre workshop. His works are held at the Musée Gallé-Juillet, Musée de Grenoble, Musée d'art moderne André-Malraux, Musée Carnavalet, and the Musée des Beaux-Arts de Pau. A street in the 17th arrondissement of Paris bears his name.
