Non-musical history for today: 1942 – Actress Hedy Lamarr and composer George Antheil received a patent for a Frequency-hopping spread-spectrum communication system that later became the basis for modern technologies in wireless telephones, two-way radio communications, and Wi-Fi. This early version of frequency hopping utilized a piano roll to switch among 88 frequencies, making radio-guided torpedoes harder for enemies to detect or jam. Lamarr and Antheil later donated the patent to the U.S. Navy.
