Heddy Lamar Did Not Invent Frequency Hopping

 I'm just a little tired of seeing this trope on various social media platforms.

Heddy was a beautiful women, she ran naked through the woods and was filmed doing it, which was the basis for her later success, but she really did not have a head for engineering. She mostly just stole stuff from the men around her and acted as a marketing girl. 

It is true that Lamarr and her unlikely partner, the radical modernist composer George Antheil, hold a patent for an important radio-transmission method that finds its way into several modern communications technologies, including Bluetooth. But it is equally true that their patent was hardly the first in this area. It is further true that the earliest operational systems employing this technique were created after World War II independently of their patent, and the essential idea can be traced back nearly to the birth of radio itself.

And more:

Now incontestable evidence shows that the U.S. Patent Office itself dismissed the idea that Lamarr and Antheil were first to propose frequency hopping. David R. Irvin, a patent agent and engineer with 44 patents to his credit, has examined the original documents related to the invention, which are preserved by the Patent Office and the Smithsonian Institution’s National Museum of American History

Abstract: Analysis of primary-source documents archived by the Smithsonian's National Museum of American History and the U.S. Patent Office refutes the widely accepted legend that actress Hedy Lamarr and musician George Antheil invented frequency hopping spread spectrum (FHSS) communication.
