I’m quoting from The New York Times, because that’s where I saw the article in the first place (on the home page) and the link shouldn’t require registration. The photo’s from good ol’ LATimes.com, though.
Loyd C. Sigmon, the inventor of SigAlerts, the broadcast messages that warn Southern California drivers of freeway traffic jams, died on Wednesday in Bartlesville, Okla. He was 95.
The first SigAlert was broadcast on Sept. 5, 1955, by six radio stations. It urged doctors and nurses to respond to a train derailment outside Union Station in downtown Los Angeles. The system was also used to report rabid dogs, a ship collision, a pharmacist’s potentially fatal error in filling a prescription and the impending collapse of the Baldwin Hills Dam in 1963.
Mr. Sigmon was honored by governments, broadcasting organizations and the National Safety Council. He even had personalized license plates that said SIGALRT.
Rabid dogs. Seriously.
Rest in peace, Loyd.
