Hedy Lamarr was an inventor
Hedy Lamarr, though best known for her beauty and status as a Hollywood celebrity in the 1930s and 1940s, was also an inventor. She was a brilliant woman who developed the concept of frequency-hopping technology, which laid the groundwork for Wi-Fi, Bluetooth, and GPS technologies.
However, Hollywood wanted to see her as little more than a beautiful face. Despite the fact that she and co-inventor George Antheil filed for a patent, she never received acclaim or compensation for her idea.
