L'Escalier de Cristal, is the name of a Parisian company created around the year 1800 by Madame Veuve Desarnaud, known for her decorative objects in which she combined crystal and bronze. She was awarded a gold medal at the Paris exhibition, "Exposition des Produits de l'Industrie" in 1819, for an exquisite dressing table in gilt bronze mounted in crystal.

Located in Paris, at the Palais-Royal, the well-known boutique L'Escalier de Cristal was bought around 1830 by Boin and then by Lahoche in 1840. The company had its rise to a position among the most important Paris stores for decorative goods. Lahoche, who greatly expanded the business, later went into partnership with his son-in-law to start Lahoche et Pannier in 1852.

In 1872, Emile Pannier alone managed the company, and then his sons from 1885 to 1923. They eventually changed the name of the company to Pannier Frères, which was then located on the corner next to the newly built Paris Opera.

L'Escalier de Cristal was awarded several times with medals at the various international exhibitions held in Paris, London and New York, and was awarded, for example, a gold medal at the World Exhibition in Paris in 1900.

Many artists, such as Emile Gallé, Louis Majorelle and Gabriel Viardot worked for L'Escalier de Cristal and introduced some of their greatest creations in the Japanese style (adorned with "cloisonné" enamels, Japanese motifs) to the company.
Paul Canaux & Cie was located in Paris at 75 Boulevard Malesherbes during the period 1892 - 1911..
