drowsy maggie played backwards contains satanic messages

We've been learning about the playfair cipher in my security class... It's a relatively simple method for encoding a message into an unreadable string that can only be derived if you know the system used and
and I did some homework using it last night...
It was the most popular cryptographic cipher for a very long time, and used heavily in WW I and still some in WW II.


I just went online to find out more about it...
and read a little bit of history... :

"In 1854, Sir Charles Wheatstone invented the cipher known as "Playfair," named for his friend..." blah blah blah, etc, etc...

except that it's CHARLES WHEATSTONE.

the... get this...
inventor of the concertina.
