The historian Paulina Bren, in her new book, The Barbizon: The Hotel That Set Women Free (Simon & Schuster), chronicles the experiences of these women, and of some of the hundreds of thousands of others like them, who stayed in the hotel. More than a biography of a building, the book is an absorbing history of labor and women’s rights in one of the country’s largest cities, and also of the places that those women left behind to chase their dreams. In Bren’s telling, some of the same forces that brought them to Manhattan led to the end of the Barbizon as they knew it—and to the New York City that we know today.
