There’s a reason we use the term “Roaring Twenties” to describe the decade between World War I and the Great Depression: Among other firsts, it was the first time in American history that more people lived in cities than in rural areas. During those years, New York City buzzed with the rumble of automobiles, street hawkers shouting about their wares, and, of course, jazz. The Lost Generation—Fitzgerald and Hemingway among them—drifted from New York to Paris looking for excitement, literary inspiration, and a great meal. In New York, Prohibition drove wild parties underground, where bootleggers served bathtub gin in teacups and gangsters kept the police in their pockets. It was a time of decadence and glamour.
