1881. Poet and painter Rudolphe Salis invited a bunch of artists, musicians, performers, writers, satirist and intellectuals to his apartment in Montmartre, Paris. This became a weekly ritual with more and more people attending the party until it eventually spread next door. Of course funding such events got expensive, so Salis began selling drinks. What began as a party became a business, what Salis called a cabaret -- a medieval word meaning wine cellar or tavern.
