Discover the role of women in World War II in this video from the American Masters film Bombshell: The Hedy Lamarr Story. Hedy Lamarr invented frequency hopping—a technology that could have provided a significant advantage to the United States military in the war—but the Navy shelved her idea and told her to sell war bonds instead. By selling war bonds, she engaged in something deemed more appropriate for a woman, especially a glamorous actress. In this resource, students explore the opportunities open to women during the war through discussion questions, a background essay, a student handout analyzing primary sources, and other tips for extending learning.
