I haven't seen anybody point at this URL

        http://cm.bell-labs.com/cm/cs/who/dmr/hist.html

where you can read about early Unix story from the horse's mouth
himself. The paper is 20 years old, but still full of very tasty
tidbits. Browse around and you'll find many more interesting goodies.
In particular, if you want to know the story of how C came to be, as
told by its creator, try this URL

        http://cm.bell-labs.com/cm/cs/who/dmr/chist.html

Take it from somebody who has been hacking all sorts of Unix and
Unix-like kernels for the last 25 years: Those who don't know Unix
history are doomed to reimplement it badly.
