In 1942, actress Hedy Lamarr and composer George Antheil received U.S. patent 2,292,387 for their "Secret Communications System", [9] [10] an early version of frequency hopping using a piano-roll to switch among 88 frequencies to make radio-guided torpedoes harder for enemies to detect or jam.

The following is a list of celebrity inventors and their patents. (For the purposes of this article, an inventor is a person who has been granted a patent.)After Google released a patent search [1] online in December 2006, a website called Ironic Sans, [2] made the public aware of a number of celebrity patents found through the new patent search engine.
Hedy Lamarr and co-inventor, George Antheil, worked on a frequency hopping method to help the Navy control torpedoes remotely. [62] The Navy passed on their idea, but Lamarr and Antheil received a patent for the work on August 11, 1942. [ 62 ]
Techniques known since the 1940s and used in military communication systems since the 1950s "spread" a radio signal over a wide frequency range several magnitudes higher than minimum requirement. The core principle of spread spectrum is the use of noise-like carrier waves, and, as the name implies, bandwidths much wider than that required for ...
