Book excerpt: Homberger focuses on four main characters who played important roles in various reform efforts of the period: Ann Lohman, known as "Madame Restell, the world-renowned medical expert," whose services as an abortionist were partly responsible for the creation of a harshly repressive public policy toward abortion that persisted for more than a century; "Slippery Dick" Connolly, comptroller of New York City, who escaped to Europe with millions of the city's dollars and betrayed his confederates in the Tweed Ring; Dr. Stephen Smith, a young surgeon at Bellevue Hospital, who was able to show that dozens of cases of typhus had originated in a single tenement on East 22nd Street; and Frederick Law Olmsted, the architect-in-chief of Central Park, who brought into reality a concept promoted by the aristocracy for the benefit of rich and poor alike.
