Editor's Take:

Hedy Lamarr was sold by Hollywood as the most beautiful woman in the world. Few people knew she spent her evenings inventing. During the war she and composer George Antheil patented a system that switched radio frequencies to stop enemies jamming torpedoes. The navy ignored it at the time. Decades later, similar ideas helped wireless technology. She got proper credit only late in life. She is now celebrated by inventors as well as film fans.
