A fact I didn't know: At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers. Although the US Navy did not adopt the technology until the 1960s, the principles of their work are now incorporated into modern Wi-Fi, CDMA, and Bluetooth technology, and this work led to their induction into the National Inventors Hall of Fame in 2014. Their invention was granted a patent on August 11, 1942 (filed using her married name Hedy Kiesler Markey). However, it was technologically difficult to implement, and at that time the U.S. Navy was not receptive to considering inventions coming from outside the military. Only in 1962 (at the time of the Cuban missile crisis) did an updated version of their design appear on Navy ships.[ The design is one of the important elements behind today's spread-spectrum communication technology, such as modern CDMA, Wi-Fi networks, and Bluetooth technology.

In 1997, they received the Electronic Frontier Foundation Pioneer Award and the Bulbie Gnass Spirit of Achievement Bronze Award, given to individuals whose creative lifetime achievements in the arts, sciences, business, or invention fields have significantly contributed to society. She was featured on the Science Channel and the Discovery Channel. In 2014, Lamarr and Antheil were posthumously inducted into the National Inventors Hall of Fame.(Wikipedia).
