This:

http://www.softpanorama.org/People/Shell_giants/introduction.shtml

has the timeline mostly correct; but the author is so far off on the
relative merits of the Bourne and C shell scripting languages, for
example, as to make most of his editorializing ignorable.  He seems
to have some kind of axe to grind with Steve Bourne and wastes a lot
of words bashing him (no pun intended), but there is a lot of useful
source material quoted or linked.

I almost stopped reading when he started to foam at the mouth, it ruins the document. Anyway thanks, that's as much of a brief history as I need. One thing tho:

"no clean separation between lexical analysis and syntax analysis"

I sure can agree with that, it seems to be at the heart of many difficulties.
