This article describes a new curriculum which explores a disturbing side of the Progressive Era. The national education program Facing History and Ourselves is a 25-year-old organization best known for its trenchant examination of the Holocaust and other genocide campaigns. Facing History discovered in the course of that work that many of the Nazis' ideas about superior and inferior human worth had origins outside Nazi Germany. To explore that development, the program has recently launched a new initiative focusing on the eugenics movement, an attempt in the early 20th century to solve social problems by "eliminating inferior racial traits." The project's centerpiece is the resource book Race and Membership in American History: the Eugenics Movement, compiled by Phyliss Goldstein and Alan Stoskopf, with assistance from Karen Murphy. An online instructional module and hands-on training workshops help middle and high school teachers weave the eugenics theme into existing history, literature and science curriculum.
