He was a pupil of Rodolphe Kreutzer for the violin and Auguste Barbereau, Jean-François Lesueur and Antoine Reicha for composition.

The Théâtre des Variétés took a real boom under the direction of Nestor Roqueplan who presented plays by Lockroy (Le Chevalier du Guet, 1840, On demande des professeurs, 1845, Les Trois coups de pieds, 1851), Alexandre Dumas (Halifax, 1842), Théophile Gautier (Le Tricorne enchanté, 1845), Eugène Labiche (Oscar XXVIII, 1848, Madame veuve Larifla, 1849, Un Monsieur qui prend mouche, 1852), Alfred de Musset (L’Habit vert, 1849), George Sand (La Petite Fadette, 1849) and operettas by Jacques Offenbach (La Femme à trois maris, 1853, Pépito, 1853).

Thus Nargeot wrote many songs, tunes, quadrilles, rondes, inserted in these plays, especially in the Tricorne enchanté by Théophile Gautier (1845) and Le Lion empaillé by Léon Gozlan (1848).

In 1853, Nargeot left the Variétés and joined, as violist, the orchestra of the Imperial Chapelle, which Napoléon III had just reopened.

He spent the rest of his life composing, trying to represent his operettas on stages of Parisian boulevards and died in Paris at age 92.
