That seemed very unfair. So I just looked it up. Antheil and Lamarr donated their patent to the U.S. Navy.
Respect to them. Not every hero wears a uniform.

Ii’m old enough to remember WW2, in fact I was listening to the radio while mom, dad, and a guest couple ate Sunday Dinner (midday back then). I heard Roosevelt’s voice saying “We are at war” and rushed into the dining room to tell the adults. Of course the entire country listened to radio news every night. Totally aware what war meant.
Very clear memories of that fateful day. Dad had taught me to read at 4. Picked up picked up novel “Dwarf’s Blood” to read while waiting for adults to finish meal. Probably thought it was a kid’s book. Bought a copy on eBay a few years ago.
