I am working on (the book proposal for) Teaching Machines, and I plan to include a chapter on Norman A. Crowder, inventor of the TextTutor and AutoTutor.

Much of my research on other twentieth century inventors of teaching machines involves my visiting university archives to see their papers. (I visited The Ohio State University over Spring Break to look at Sidney Pressey’s for example, and I’ve scheduled trips to Harvard and Stanford to see B. F. Skinner’s and Patrick Suppes’s respectively.)
But I’m struggling to find if and where Crowder’s papers exist. (That is, his letters and so on.) He had stints at several universities, including Illinois Technical College. He worked for a while in business at for the military.
