Why did hedy lamarr invent spread spectrum technology?

Hedy Lamarr co-invented spread spectrum technology during World War II as a means to enhance secure military communications. Alongside composer George Antheil, she developed a frequency-hopping technique to prevent enemy interception of radio signals used for guiding torpedoes. Their invention aimed to improve the reliability and security of military operations, ultimately laying the groundwork for modern wireless communication technologies. Lamarr's contributions were largely unrecognized during her lifetime but are now celebrated for their impact on telecommunications.
