The Francois Marquis house is a chocolate and confectionery factory and a tea and coffee trade. It was founded, Passage des Panoramas, in 1818. In 1813, the brothers Louis and François MARQUIS had a certain reputation in Paris, by running a grocery business at 41 rue Helvétius and by manufacturing and selling chocolate there. But the company was dissolved. Louis, who had married a confectioner from the rue des Lombards, Mrs. widow GUELAND, kept the chocolate fund operated rue Sainte-Anne (formerly rue Helvétius). For his part, François founded his own business in 1818 at 59 Passage des Panoramas. In the 1830s, the F. Marquis company occupied numbers 57 and 59 of this straight passageway linking boulevard Montmartre and rue Saint-Marc. This place, very popular since the French Restoration, owed its fame to its teas and chocolates that wealthy walkers of the Chaussée-d'Antin came to buy, as well as sweet confectionery. MARQUIS produced his chocolate in his factory located at 21 rue Boinod. An excellent chocolatier, Mister MARQUIS was also a man of letters and a scholar, and has made himself the responsible editor of most modern poets. François-Philibert MARQUIS succeeded his father. He continued to face the unfair competition that his brand had aroused for decades. Indeed, the business of Louis MARQUIS (the less successful brother of François MARQUIS), rue Sainte-Anne, knew successive buyers who did not fail to want to take advantage of the notoriety and vogue of the house F. Marquis, of the Passage des Panoramas. To complete the confusion, in 1870, one of them, called PERCHERON, who had set up his new store at 10 rue de Richelieu, made sure that the name "former L. Marquis house" was not seen by the public and only kept "Marquis" brand. Maison F. Marquis became a limited company in 1920. When it absorbed the confectionery-chocolate Marquis-Siraudin, located at 19 boulevard des Capucines, this place was renamed F. Marquis. From 1935, the two brands were united there, with their specialties. The Marquis house disappeared in the 1950s.
