Pearl “Polly” Adler (1900-1962) was a diminutive dynamo whose Manhattan brothels in the Roaring Twenties became places not just for men to have the company of women but were key gathering places where the culturati and celebrity elite mingled with high society and with violent figures of the underworld—and had a good time doing it.
