I have now decided that I must expand the scope of my work on John Henry. Having some good new material on the interaction between Guy Johnson and Louis Chappell, I feel that I must look into that more closely and not just dismiss it with a few sentences as others have done. That means that I must visit the archives at West Virginia University, Chappell's papers, and try to learn a lot more about Chappell, and Johnson, too.
Right now my impression of Chappell is that he was a brilliant, highly accomplished scholar who might not have gotten the recognition he deserved at West Virginia University in a timely fashion. Eventually, it came, I think, but that is one of the matters I hope to look into.
