In 1944, actress and inventor Hedy Lamarr, alongside composer George Antheil, developed a frequency-hopping spread spectrum technology to secure radio communications for torpedoes. While initially overlooked by the military, this innovation laid the groundwork for modern wireless communications, including Wi-Fi and Bluetooth. Lamarr's pioneering work in telecommunications has had a profound impact on the development of contemporary wireless connectivity, illustrating her significant contributions beyond her acting career.
