Obligatory shoutout to Hedy Lamar
(wiki) Lamarr is also credited with being an inventor. At the
beginning of World
War II <https://en.wikipedia.org/wiki/World_War_II>, she and composer George
Antheil <https://en.wikipedia.org/wiki/George_Antheil> developed a radio
guidance system for Allied
<https://en.wikipedia.org/wiki/Allies_of_World_War_II> torpedoes
<https://en.wikipedia.org/wiki/Torpedo>, which used spread spectrum
<https://en.wikipedia.org/wiki/Spread_spectrum> and frequency hopping
<https://en.wikipedia.org/wiki/Frequency_hopping> technology to defeat the
threat of jamming <https://en.wikipedia.org/wiki/Radio_jamming> by the Axis
powers <https://en.wikipedia.org/wiki/Axis_powers>.[5]
<https://en.wikipedia.org/wiki/Hedy_Lamarr#cite_note-EFF1997-6> Although
the US Navy <https://en.wikipedia.org/wiki/US_Navy> did not adopt the
technology until the 1960s, the principles of their work are arguably
incorporated into Bluetooth <https://en.wikipedia.org/wiki/Bluetooth>
technology, and are similar to methods used in legacy versions of CDMA
<https://en.wikipedia.org/wiki/CDMA> and Wi-Fi
<https://en.wikipedia.org/wiki/Wi-Fi>.[6]

<https://en.wikipedia.org/wiki/Hedy_Lamarr#cite_note-NYT19412-9> This work
led to their induction into the National Inventors Hall of Fame
<https://en.wikipedia.org/wiki/National_Inventors_Hall_of_Fame> in 2014.[5]
