A precise 1821 engraving by Ambroise Tardieu depicting the French chemist André Laugier, presented in a formal oval portrait style.

This engraving by Ambroise Tardieu depicts the French chemist André Laugier. Produced in 1821, the work adheres to the conventions of early nineteenth-century scientific portraiture. Tardieu, a skilled cartographer and engraver, employs a precise technique to capture the likeness of his subject, who is presented within a clean oval frame. The composition is balanced, focusing on the sitter's facial features and formal attire, which reflects the professional status of a man holding positions at the Jardin-du-Roi and the Académie royale de Médecine.

The print includes detailed biographical text below the portrait, documenting Laugier's academic titles and his birth date in 1770. Such prints were common in the period, often circulating among scientific societies to commemorate members and document the appearance of notable intellectuals. The stipple and line work used in the engraving creates a subtle tonal range, providing a sense of volume to the face and clothing without relying on heavy shadows. The background within the oval is kept minimal, ensuring the viewer's attention remains on the subject.

As a historical document, this print provides a clear record of Laugier's appearance during his active years in Paris. The clarity of the engraving reflects the technical standards of the era, where precision was valued for both scientific illustration and portraiture. The work is a fine example of the intersection between the arts and the scientific community in post-revolutionary France, where the documentation of individuals was a standard practice for institutional archives and personal collections alike.
