It is a nice story but I am not so sure that Lamar’s patent was consequential to later developments of frequency skipping. Due to the technical limitations of radio at the time, Lamar’s patent was never more than a bare idea without an actual device being developed. Only when other researchers investigated and patented frequency skipping devices years later in other contexts did Lamar’s patent come to light in the research for their patents.

Wrong. It was a precursor to GPS and WiFi

Not bad. For a girl. Not bad for Rambo.

“ During World War II, actress Hedy Lamarr co-invented a “Secret Communication System” to prevent enemy jamming of Allied radio-controlled torpedoes. Together with composer George Antheil, she developed frequency-hopping spread spectrum technology to secure naval torpedo guidance, which was patented in 1942. While initially ignored by the Navy, this invention became foundational to modern Wi-Fi, Bluetooth, and GPS”
