Today's puzzler is rooted in some deep history. 

Here we go. This one involves the name Hedwig. 

During World War II, many of our stars in Hollywood contributed to the war effort. You know, Bob Hope traveled the world entertaining troops and brought along his entourage. Betty Grable, Jane Russell... Many others too. Everyone at that time did their part. 

But one Hollywood star contributed in a different kind of way. Instead of going to the front lines and entertaining the troops, this star actually invented something that is still in use today. And what the star invented was a device that would not allow the enemy to jam our radio transmissions. It was a frequency hopping device. 

So for instance, you could transmit on one frequency talking to one of your commanders, and then the frequency would hop to another, and then another on down the line, and the enemy couldn't jam the transmission because it was hopping like that. So you'd always be able to broadcast on some frequencies that were transmittable and receivable. 

This person invented a device to do that. This person has a patent on it. And the question very simply is, 'Who is this person?'

And I'm going to give you this person's first name. The first name is Hedwig. 

But what was this person known as in Hollywood?

Good luck.
