A. All were invented
by women.
Seems to be a disagreement on the last item, seems Gary Starkweather
is widely credited with the laser printer. It is, of course,
just a Xerox dry photocopier with a device to put the image on
the drum electronically, instead of lenses imaging the paper
original. It's one of those "DAMN! Why didn't I think of that!"
inventions.

You have to admit, at maybe almost 50% correct, this is one of Runner's

Likely the idea arose from George Antheil's efforts to synchronize
multiple player pianos. The difficulty isn't changing frequencies,
it's having the receiver know exactly when to switch to the next one.

Lamarr's first husband had been an Austrian munitions maker so she was
aware of the technologies and problems.
