The One-Two-Two was one of the most luxurious and illustrious brothels of Paris in the 1930s and 1940s. The name was taken from the address, 122 Rue de Provence, 8th arrondissement of Paris. The numbers were translated into English to ensure that foreign tourists would be able to find the brothel and as a password for French people.

Le Chabanais was one of the best known and most luxurious brothels in Paris, operating near the Louvre at 12 rue Chabanais from 1878 until 1946, when brothels were outlawed in France. It was founded by the Irish-born Madame Kelly, who was closely acquainted with several members at the Jockey-Club de Paris. Among the habitués were Albert, Prince of Wales ; Henri de Toulouse-Lautrec; Cary Grant; Humphrey Bogart, Mae West and diplomatic guests of the French government.
