Summary: Most people know Hedy Lamarr as a film star, but she was also a dedicated inventor who spent her spare time coming up with ideas like a glow-in-the-dark dog collar and a flavor cube to turn plain water into soda. Her biggest invention, working with composer George Antheil, was the “frequency hopping” guidance system, designed to prevent the enemy from jamming radio signals on torpedos. She and Antheil received a patent for their work in 1942, but unfortunately the system was never implemented by the Navy during the war. Forty years later, the idea was declassified, and is used today to help keep cell phone calls and texts private. The two inventors never received recognition or money for their creation, but in 1997, they received the Pioneer Award from the Electronic Frontier Foundation. As Hedy commented, “It’s about time.” Includes a timeline, additional information about frequency hopping, a bibliography, a filmography of Lamarr’s works, and a reading list about other women in STEM. 48 pages; grades 2-5.
Pros: Who knew Hedy Lamarr was a talented scientist and inventor as well as an actress? This engaging biography includes information on her both her careers; the lively illustrations incorporate relevant quotes from Lamarr. I was hoping to include a review of another book on this same topic, Hedy and Her Amazing Invention by Jan Wahl, published the same week, but no one in my library network has gotten a copy of this one.
Cons: Some of the technical details may be a bit much for younger readers.
