Without today’s birthday boy, we would have never experienced great radio shows like The Shadow, or made out in the moonlight serenaded by Duran Duran. Alan Hazeltine was born today in 1886. He was an engineer, inventor, physicist and professor, but his greatest claim to fame was the neutrodyne circuit, which squelched noise while boosting good signal. This circuit made commercial radio a viable business model in the early 1920s.
While progress would push past his circuit to better technology, he still scored a cool $3 million for his patents by the end of the decade, and did what any of us would do: go to Europe for a nice long vacation to study art, and, since he was a geek, study math too.
After his sweet vacay, Hazeltine came back to the U.S. and once again picked up his teaching job at the Stevens Institute of Technology. He consulted and also had a hand in the development of television.
He passed away in 1964, but we still want to thank him for all those great tunes and radio plays that came along because of his invention, from the country-wide freakout during the War of the Worlds broadcast to the original Hitchhiker’s Guide to the Galaxy series. Then again, he also paved the way for A.M. talk radio and not-so-wacky morning DJs.Tweet
