I think the gender really is key here, since Heddy's sole contribution was co-authoring a single patent to use piano rolls to generate coded messages. I guess you can call this "weapons research" in the sense that cryptography is sometimes considered munitions. But it wasn't very good cryptography and didn't end up being used, so I don't think anyone would care about this except for Heddy being turned into a type of "women in science" icon, with people then claiming that the piano roll was really spread spectrum, so Heddy invented spread spectrum, and others claiming that the piano roll meant she invented GPS, cell phones, etc. It's really out of control.
This is unfortunate as there are many accomplished women in science who are real scientists and who made real contributions, but are not well known because there is no Hollywood star angle to tie in, just actual science. For example my favorite female researcher would have to be Karen Uhlenbeck, whom no one in popular culture has heard of, but who was (IMO) the most brilliant female mathematician of the last 100 hundred years. There are many such examples of unknown women scientists if we look for real inventors and real scientists, rather than looking for someone "sexy" to make into an icon for our favorite causes.
- eindiran 7y ago> Karen Uhlenbeck, whom no one has heard of, but who was... Not sure what you mean: she's pretty famous from having won the Abel Prize (and being the first woman to do so).
- rsj_hn 7y agoRight, in the scientific community, but not many people know about the Abel prize or have heard of Uhlenbeck's bubbling results.
- eindiran 7y agoThat's fair point. I interpreted your comment to mean that she was unduly unrecognized in the academic world, but I agree that venturing out into the wider world, she's probably not well known at all.
- rsj_hn 7y agoCorrect, Uhlenbeck was given the proper recognition in the mathematical community, but people outside that community don't know her. She is not an icon for Women in Science and neither is someone like Emmy Noether, or even in the world of cryptography, someone like Shafi Goldwasser -- they are all unknown. But instead an actress with zero scientific research publications, no PhD, and just this one piano roll patent that she sent, unsolicited, to the Navy which rejected it -- she is high on the marquee for "women in science". That's a shame.
- AnimalMuppet 7y agoIt was using piano rolls to control frequency hopping, not as cryptography. The intent was to make radio-controlled torpedoes more difficult to jam. That's far more munitions than just "cryptography is munitions".
- rsj_hn 7y agoIn modern parlance, it's not munitions at all. But yes, Antheil and Lamarr's proposed device was trying to hide the signal so that it would be harder to jam by hopping along one of 88 frequencies which were marked in the piano roll. This is a form of cryptography. Any algorithm meant to authenticate, sign, or hide information is cryptography, and any attempt to break such techniques is cryptanalysis. Currently we do not like to think of cryptography as munitions due to the crypto wars of the 90s. But however you fall on that debate of whether cryptography is munitions, it is misleading to consider someone volunteering their time in an unprofessional capacity to send an unsolicited patent to the Navy, which the Navy rejected, as being equal to working in "munitions research"
