Yes I do mean automated stepping; I didn’t realize there were so many 
sub-developments:  A goniometer driven by a stepper motor with a counter/timer 
monitoring the output from the detector.

Younger than you thought?!?  This is a first!

Subject: Re: Automated XRD Date

By automated I mean simply producing digital data, in x y pairs

I assumed you meant automated stepping. If you mean just digital data, then its 
Shull and Wollan in the late 1940's. Neutrons were always digital of course; we 
had film and cameras much later than for x-rays.

You must be younger than I thought Jim, with your 1980 memories, or else I am 
older than I think :-)

Alan.
