The United States Navy made a mistake by rejecting the technology developed by Lamarr because this decision was due to the prejudice that she was a woman even though her technology was revolutionary and useful.
Hedy Lamarr (1914n 2000), was a prominent Austrian film actress and inventor who contributed to the invention of the first version of the spread-spectrum that would allow long-distance wireless communications.
The invention of wireless communications developed by Hedy Lamarr had the support of George Antheil during the beginning of World War II. This technology allowed the creation of a radio guidance system for torpedoes that used spread spectrum and frequency hopping technology to overcome the threat of interference from enemies.
However, this technology at that time was discarded by the United States Navy because they believe it was ineffective for being developed by a woman. Later, towards the sixties, it was adopted and was a determining factor in military and telecommunications technology worldwide.
