Augier was born at Valence, Drôme, the grandson of Pigault Lebrun, and belonged to the well-to-do bourgeoisie in spirit as well as by birth. After a good education and legal training, he wrote a play in two acts and in verse, La Ciguë (1844), which was refused at the Théâtre Français, but produced with as considerable success at the Odéon. This settled his career. From then on, at fairly regular intervals, either alone or in collaboration with other writers—Jules Sandeau, Eugène Marin Labiche, Édouard Foussier—he produced plays such as Le Fils de Giboyer (1862) - which was regarded as an attack on the clerical party in France, and was surely brought out by the direct intervention of the emperor. His last comedy, Les Fourchambault, belongs to the year 1879. After that date he wrote no more, restrained by the fear of producing inferior work.

He died at his home at Croissy-sur-Seine.
