An early 20th-century reform writer and physician, she wrote forceful, sensational books about prostitution, trafficking, and what she saw as urban moral danger. Her work offers a vivid window into Progressive Era social-purity campaigns and the fears that shaped them.

by Jean Turner-Zimmermann
Jean Turner-Zimmermann, also identified in historical records as Dr. Charlotte Jean Turner Zimmerman, was an American physician and writer active in the early 1900s. She is known for books including Chicago's Black Traffic in White Girls, White or Yellow, and Vere, of Shanghai, works that tied her to the social-purity reform movements of her day.
Her writing focused on prostitution, trafficking, race, and immigration, and it often used dramatic, warning-filled language meant to stir public concern. Today, those books are useful less as neutral reporting than as documents of the anxieties, reform campaigns, and prejudices circulating in the United States during that era.
