Here’s the late David Herbert Donald in 2002 talking about his career and his research, and especially his books. This is a great discussion, marred by only two idiots who called in and made fools of themselves.
A few years back at the Civil War Institute at Gettysburg College I purchased a box of back issues of the journal, Civil War History. When I got them home I noticed they were all signed by David Herbert Donald. They were from his personal library, as he had passed away only a couple of years earlier.
