Looking for Biographical Information on World War II "4th Armored
Division" Commander Major General John Wood or Woods, not sure of his
last name.

Dear Tick, 

John Shirley (P) Wood was the commander of the 4th armored division.
Wood was an exceptional character: the "P" stood for "professor", and
was supposed to symbol his intelligence (relatively to his
contemporary collegues), his strategic depth, etc.

An article on "The Uniformed Intellectual" discusses this issue: "On
one hand he was a football player, shrewd tactician, Distinguished
Service Cross winner and extraordinarily aggressive blitzkrieger who,
as commander of the 4th Armored Division, spearheaded the reconquest
of France by George Patton's Third Army, for which Liddell Hart
bestowed upon him such honorifics as "the Rommel of the American
armored forces" and "one of the most dynamic commanders of armor in
World War II." On the other hand, Wood was a brilliantly precocious
student (having entered the University of Arkansas as a sophomore at
the age of 16 to study chemistry); a tireless tutor of less
academically gifted cadets at West Point, earning the lifelong
nickname P (for professor); a pioneer armor theorist; a devourer of
books; a gifted linguist who read Charles de Gaulle on armor in the
original French and Heinz Guderian in German; and a devotee of
Rosaceae, or what we plainer folk call the rose family." (Col. Lloyd
J. Matthews, "The Uniformed Intellectual and His Place in American
Arms: Part I", Army Magazine, July 2000,
http://www.ausa.org/www/armymag.nsf/(all)/797D92335A50B78C85256BDE004B0E69?OpenDocument).

Another article discusses Wood's depth of strategic planning, as Dr.
Christopher R. Gabel reveals in his analysis of the encirclement of
Nancy. Of copyright reasons (large parts of the article disuss Wood's
character), I would not copy, and rather direct you to the source:
