Bergeret played a major role in introducing lithography, in part through his reproductive prints after paintings by Nicolas Poussin and Raphael: his lithograph Mercury (1804), reproducing a detail from Raphael’s fresco in the Villa Farnesina, and his caricature of current Paris fashion, Le Suprême Bon Ton Actuel (by 1805) are among the earliest examples of lithographic technique.Bergeret was commissioned to design Napoleonic medals, or provide frieze-like panels en camaïeu to be painted on Sèvres porcelains and to provide designs for the bas-reliefs on the Column in the Place Vendôme, built 1806–11 in direct competition with Trajan's Column in Rome.
The Column has had a checkered career, destroyed and replaced twice.
The subjects of his paintings tend towards the vividly anecdotal.
He was early among artists drawing subject matter from the culture of the Renaissance, in the style Troubadour: Honors Rendered to Raphael on His Deathbed 1806 (Allen Art Museum, Oberlin College, Ohio).
