Monsieur Merlen

The carte-de-visite, a small photograph mounted on card stock, was patented by André Adolphe-Eugène Disdéri in 1854. This efficient, inexpensive process employed a camera with four lenses and a sliding plate holder that produced eight sequential exposures on a single glass negative. The resulting paper print was cut into individual images. This uncut sheet, which includes several humorous views, was probably produced for the sitter’s approval. The low cost of the carte-de-visite led to the trend of collecting celebrity portraits. By 1862, Disdéri’s studio was producing over 2,000 prints a day, making him reputedly the world’s richest photographer.
