Thanks, Ashtom. Fascinating!
I read about her husband in the
"Code Breakers" (by David Kahn) back in 1967, and still recall that he came up with a test that showed that ciphertext had information without knowing what that information was.
Dollars to donuts she had a hand in that!

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
-- Isaac Asimov
