Tonight on American Masters, discover the ingenious inventor behind the pretty face.

Hollywood star Hedy Lamarr was known as the world’s most beautiful woman—Snow White and Cat Woman were both based on her iconic look. However, her arresting appearance and glamorous life stood in the way of her being given the credit she deserved as an ingenious inventor whose pioneering work helped revolutionize modern communication: her pioneering work is the basis for secure WiFi, GPS and Bluetooth. The Hollywood star tells her own story in a newly discovered interview.

Watch American Masters: Bombshell: The Hedy Lamarr Story tonight at 9pm on WGBH 2.
