Bracketed by the catastrophes of the Great War and the Wall Street Crash, 1920s America was a place of drama, tension and hedonism. It glittered and seduced: jazz, flappers, wild all-night parties, the birth of Hollywood, and a glamorous gangster-led crime scene flourishing under prohibition. But the period was also punctuated by momentous events – the political show trials of Sacco and Vanzetti; the huge Ku Klux Klan march down Washington DC’s Pennsylvania Avenue – and it produced a splendid array of writers, musicians and film stars, from F. Scott Fitzgerald to Bessie Smith and Charlie Chaplin.
