Celebrities having an interest in the hard sciences

Lamarr was Austrian, and during WW2 the US was at war with Austria. It's not surprising. By the way, this invention is also used in Wifi.

She was also from a Jewish family which should more or less automatically have meant this was not an issue. There were plenty of German and Austrian Jews who fought on the allied side during WWII and many of them had access to classified information, not to mention all the Jewish scientists who did not seem to have much trouble getting the necessary security clearance to work on very sensitive projects.

Hence, I agree with Statguy2000: the fact that she was Austrian can't have been the reason.
