``The "From: " header'' and ``The envelope "from " header''---I knew I
was confused the first time I read the message...

The address listed in the From field is what I call the header sender.
There could be a different official name for it though.

That's what I (and most people I know of) call the envelope sender, and
it does not appear in the header (unless your mailer puts it into the
Return-Path field, but it's not an obligatory behaviour).
The other thing that should be clarified is that there is _one_ header
in a message, consisting of one or more fields. For more definitions,
see http://cr.yp.to/immhf/header.html.
