"Beyond putting himself as the poet Rodolfo, [Henry] Murger created his characters based in some real persons, such as the painter and composer Alexandre Schanne (prototype of Schaunard), the theologist Jean Wallon (mold of Colline), and the painter François Germain Léopold Tabar (model of Marcello). Without mentioning the Café Momus, which until its closure, in 1850, it was at number 17 of rue des Prêtres-Saint-Germain-l'Auxerrois, between the Louvre and Pont Neuf." (Perpetuo)
