Went to a fascinating presentation put on by Dartmouth at the Robert Frost Farm where I learned that Frost headed up the effort to get Pound out of prison. He enlisted Eliot, Hemingway, Frank Lloyd Wright and others. Lots of people had issues with Pound, but if I recall correctly, Frost's attitude was, this guy has helped us and we can't just let him rot away in prison. Their efforts were successful.
