In 1942, Hollywood actress Hedy Lamarr and avant-garde composer George Antheil received US Patent 2,292,387 for a frequency-hopping radio system synchronised by a perforated paper roll borrowed from a player piano, a technique the Navy filed away as unworkable and which now underpins every Wi-Fi router, Bluetooth earbud, and GPS receiver on Earth.

On August 11, 1942, the US Patent Office issued Patent No. 2,292,387 to Hedy Kiesler Markey, the legal name of MGM star Hedy Lamarr, and her co-inventor George Antheil, a composer best known for a 1920s ballet scored for multiple synchronised player pianos, airplane propellers, and a siren. The patent described a “secret communication system” for keeping a radio signal from being jammed or intercepted by switching it rapidly among many carrier frequencies, hopping between them in a pattern set by a perforated paper roll identical to the ones that drove player pianos. The idea was to guide a radio-controlled…

How Physician Couples Should Structure Their Finances (And Why Most Don’t Talk About It Honestly)

Passive Income

I want to start with a question I hear a lot, usually from physicians in the middle of some kind of transition. “Are we actually okay financially?” Sometimes it comes up when someone is thinking about cutting back clinically.

Here’s where the best savings rates stand today — and what…

When the U.S. military finally deployed frequency-hopping spread spectrum on Navy ships during the 1962 Cuban Missile Crisis blockade, the patent that described the technique had expired three years earlier, and its inventor was watching the news in a Los Angeles bungalow without any idea her idea was at sea.

Saving Tips

On August 11, 1942, the U.S. Patent Office granted Patent No. 2,292,387 for a “Secret Communication System” to two inventors with unusual day jobs. One was the avant-garde composer George Antheil, who had once scored a ballet for synchronized player pianos. The other was Hedy Kiesler Markey, better known to American audiences as Hedy Lamarr, the MGM contract actress being marketed as “the most beautiful woman in the world.” The patent described a method for guiding a torpedo by radio without the signal being jammed. The transmitter and receiver would jump together across 88 different frequencies in a pattern set…
