Unhappily married to a Nazi arms dealer, future Samson and Delilah star Hedy Lamarr fled to America at the start of World War II, bringing her talent and considerable notoriety but also a gift for technical innovation. After making the acquaintance of Ballet méchanique composer George Antheil at a Hollywood dinner, they joined forces to devise a radio guidance system for torpedoes—a forerunner of current digital technology—the unlikely duo's gift to the U.S. war effort. Illustrated with 8 pages of black and white photographs, this history by the Pulitzer Prize- and National Book Award-winning author of The Making of the Atomic Bomb tells a glamorous but often overlooked tale from the "Greatest Generation."
