[ih] Early History of the Internet

[Vint Cerf]

thanks for this, Brian. As far as I know, Louis built only the Cigale and
connected hosts to it.
However, it is certainly believable that he was thinking about and writing
about interconnection.
His "Catenet" idea is evidence of that. I used that term in INWG note 48
but later went with "internet"
