Subject: J. Tuzo Wilson

One of Wilson's papers which I find most interesting is his 1954
"The Development and Structure of the Crust" in Kuiper's _The Earth as
a Planet_.  This paper is notable as a later example of PRE-plate-
tectonics geophysics.  I find it interesting as an example of a well
developed theory on the threshhold of a scientific revolution.  Wilson
finds the "shrinking earth" hypothesis the most plausible explanation
for the compression type features, such island arcs and trenches.  The
spreading centers in the mid-ocean ridges were not yet known for what
they are.  When plate tectonics became a viable option, Wilson moved into
the lead.  This makes him a counter-example to some Kuhnists' claim that
the existing scientific paradigmists must die or retire before the triumph
of the new paradigm.
