Chris,
I believe it is generally attributed to the "Handling of Geographic
Information" - Report of the Committee of Enquiry chaired by Lord Chorley in
1987. See also
http://www.agi.org.uk/public/what-is-agi/objectives/history.htm.
Unfortunately I do not have enough available time to delve further, but let
me know if you find the correct info.
Slainthe math,
Steven
