Among the tycoons of the Gilded Age—Carnegie, Rockefeller, Vanderbilt—is a forgotten figure: Miriam Leslie. For 20 years she ran the country's largest publishing company, Frank Leslie Publishing, becoming a tastemaker in the process. But as Betsy Prioleau details, Leslie was also a byword for scandal: She took lovers, married four times, and went to great lengths to hide her past. In this biography of the brilliant and brazen "empress of journalism," Prioleau reveals that Leslie left her multimillion-dollar estate to women's suffrage, practically guaranteeing passage of the 19th Amendment.
