Bruce,
I was not aware of the chronology of FAX invention till I started 
Googling. You're quite right that the French were the early adopters 
with the first commercial system.

I found reference to Italian physicist Giovanni Caselli, who devised a 
rival system to Bain which he called the Pantèlègraph. It was the first 
practical application and was taken up by the French government. I found 
the story at:

More stuff at:

and a Quicktime video of a pantelegraph working at:

Fascinating stuff - and Caselli's patent was earlier than Bell's patent 
for the telephone. Unfortunately it couldn't compete with the regular 
telegraph of Morse or Baudot. I think it wasn't until the 1910s when 
photelectric cells allowed photographs to be transmitted that facsimile 
came into its own for newspapers.

Cheers,
Sam
