After his conscription and before World War I, he became famous by going into the military vaudeville, a popular genre at the time with plays like Tire au flanc, Le Tampon du capiston, then Les Dégourdis de la 11e.

After the war, he collaborated with Nicolas Nancey on L'Héritier du bal Tabarin in 1919 and Il est cocu, le chef de gare in 1925.

In 1950 le théâtre du Châtelet sets up Pour Don Carlos, music by Francis Lopez, libretto by André Mouëzy-Éon.
