Note that this "Austrian-American actress" (I understand the helpful wording is aimed at non-buffs who may not recognise the name Hedy Lamarr) was a huge star in her day, an equivalent to - say - Margot Robbie.
Got her own joke name in Blazing Saddles. No greater honour.

Except this was an actual real accomplishment, whose out of patent idea was used later by the Navy: https://physicsworld.com/a/a-tale-of-two-lives/ . The application was indeed original, as evidenced by the receipt of a patent for it. You can argue with how the work is described here, but trying to claim it wasn’t a real accomplishment or is somehow comparable to someone adding a bunch of consts is absurd.

There is no proof that the Patent Office ever issued a secrecy order regarding her patent during WW2. One small detail, but there are large numbers of 'small' details with her story that add up to Lamarr's frequency hopping patent not being remotely what is being claimed it is now (foundation or inspiration of many future inventions), nor having wide ranging effects.
Independently thinking up her scheme was very impressive in itself. She was a very talented person.
But most coverage of Lamarr is modern propaganda.
Wlan is not using frequency hopping or am I mistaken?
No, but an early wireless midpoint between nascent wifi deployments and really shitty WAP in a world before data over cellular networks was Ricochet Networks. Frequency hopping over the public bands of the era (900MHz mostly I think) it was able to give decent wireless internet in the mid 90s to those of us living in supported areas of Silicon Valley. When laptops were a new thing and public wifi still years away it…

Bigger than Robbie, much bigger
Like many stories of this kind, the idea that this person "pioneered the basis" of these technologies seems massively overblown. What she and Antheil patented was a system that used frequency hopping to help guide torpedoes, using a piano roll to switch between the frequencies. They did not "invent" frequency hopping, which had been discussed in the literature for 30 years already.

This isn't a good example of pinkwashing. There's no harm in recognizing the efforts of the underdog. We valorize Nikola Tesla despite him living and dying as a failure.
Terry Davis too. Nobody needed TempleOS, but we're proud for him for trying.

And the spread spectrum as used in modern devices is not frequency hopping.
Could you explain what it is, then, and how it differs from frequency hopping?
