I may be "preaching to the choir" - looks like you've done a fair amount of "digging" already.
The division veterans association may be able to assist you in locating individuals who knew and/or served with him:
35th Infantry Division Association Post Office Box 5004 Topeka, Kansas 66605-0004
35th Infantry Division Association 4311 Womack Drive Colorado Springs, Colorado 80915-2721
There's a 134th Infantry website at < http://www.coulthart.com/134/http://www.coulthart.com/134/ > (from which you can download a copy of "134th Infantry Regiment Combat History of World War II" - if you don't already have one).
You may also want to request his deceased file (if you haven't already). You'll find instructions at Message #2112, this forum.
Question: He was attending Brown University when he was drafted?
