History of term "Grid Computing"

Hello,

I am yet another student who wants to do something with "Grid Computing"
:-) However, my question is a linguistical one: Do you know who actually
invented the buzzword "Grid Computing"? The earliest use of the term I
found is in the book "The Grid - Blueprint for a New Computing
Infrastructure" (Foster/Kesselman, 1999) ...

Kind regards,

Kai
