On this day in 1942, actress Hedy Lamarr, with help from her neighbor, the composer Georges Antheil, received a patent for frequency hopping, a technology that enabled radio-controlled torpedoes to evade enemy jamming by changing frequency in a preset seemingly random manner. Although the technology was not used in World War II, the US Navy adopted it in the 1960s. And its underlying concept was used in the 1990s for Wi-Fi communication.
