In 1935, actress Hedy Lamarr and composer George Antheil developed a pioneering frequency-hopping spread spectrum technology aimed at securing radio-controlled torpedo guidance systems. Despite its innovative potential, the U.S. Navy overlooked the invention at the time. This technology, which laid the groundwork for modern wireless communications including Wi-Fi and Bluetooth, remained underutilized for decades, illustrating an initial underappreciation of a fundamental breakthrough in communication security.
