Did You Know Hedy Lamarr Helped Invent Frequency Hopping?

There’s a longer story you can read elsewhere, but actress Hedy Lamarr invented and patented a system to help prevent torpedoes from being jammed by using frequency hopping.

Neither Hedy or her co-patenter made money from the invention because their patent expired before it was implemented in 1962, and wasn’t really acknowledged until 1997 by the EFF. The core logic to the invention is still in use today in spread-spectrum communications like Wi-Fi and CDMA. You can read more about it here. [Divine Caroline]

    "still in use today in spread-spectrum communications like..." crappy phones from VTECH, Uniden, and Panasonic - still trying to pawn off old technology in 2.4GHz & 5.8GHz frequencies when DECT is best. Oh well, they're all EXACTLY THE SAME THING anyway - one Israeli company produces over 85% of the chipset and SDK you use in your home phone.

    I found out about Hedy Lamarr when I was link-hopping on Wikipedia. An article about Half-Life 2 mentioned that a pet headcrab, Lamarr, was named after her. I wish she were alive now, in a time when her mind would be better appreciated regardless of her body. (Why does this silly new comment system merge all my paragraphs into one?)

    Hmmm, kinda reminds me of when I invented and patented a system to help prevent being torpedoed too frequently by using bar hopping.

    I recently saw something about exactly this on TV, but for the life of me, can't remember what show. Grr.

    Did you know that the Headcrab in HL2 that Kliner keeps as a pet is named after her?

    @OMG! Ponies!: So far I am floundering around in it. I hope time will give me greater insight into its good points.
  • SigmundTheSeaMonster
    Looks like she got the idea and applied it to her marriages...

    @Mondoz: Exactly. Censorship. We complain silently, star commentors don't because their stars mean even more now. Sweeeeet.

    Hedy is my heroine! I think she is probably more famous for this than her films! I found out about her as she was the inspiration behind Rachel Tyrell from Blade Runner. The sexiest woman in the world in my opinion!

    Clever girl. Pretty too; apparently she got her looks from her father. He was a plastic surgeon.

    Hedy Lamarr doesn't have the patent for this. "Hedy Kiesler Markey" does. (Her married name at the time).

    @92BuickLeSabre: I know. I've probably promoted about two dozen comments this afternoon. But I wanted to make a point with a problem with the new system.
  • RoboChop
    Yes. Slow news day I guess. I heard some guy named Nicola Tesla invented something called a radio a while ago too. He wasn't as hot though.

    I did touch on this a few weeks ago on my website (www.CharlesMobile.com) and her basic idea is what is making Qualcomm BILLIONS of $'s. Life just ain't fair, is it?

    @ludwigk: Your comment shouldn't need a reply to be the featured comment. It was far better than my Blazing Saddles quip and more insightful. And it's buried under a Show All Comments button. Thank you for a good comment.
  • Hiphopopotamus
    I remember Bob Wuhl talking about this on his Assume the Position comedy special... highly recommend that you check it out, funny and informative stuff.
  • Jestermeister
    Just when Gizmodo commenting had achieved near-perfection, they change it to this mess. It's slowed down the site by 10x and the attempt at making commenting more convenient has made it quite the opposite. I officially HATE the new design.

    Why yes, yes I did know. I used to work for a wireless networking engineering company (really shitty company), and I learned that there.

    ""Any girl can be glamorous, all she has to do is stand still and look stupid." Yes I did! I have an old issue of "American Heritage: Invention & Technology" magazine with Hedy on the cover, and its about how she came up with the idea of frequency hopping by combining the machinery of a player piano into a torpedo. But the fact that her patent mentioned a player piano, and because she had a vagina, she couldn't get the military and engineers to pay any attention to her. But there's no doubt that Hedy Lamarr was the complete package: Beautiful, smart, willing to take her clothes off on camera, and not above inventing anti-jamming technologies for torpedo guidance systems. Here's a link to their archives where you can see the issue and read the article: http://www.americanheritage.com/articles/magazine/it/1996/ Edit: Sorry for the horrid formatting, It's not me, I swear!

    Yup, interesting stuff. Someone pops up with this one every few years. We did a cover story on it in our tech magazine back around 2000.
