Oh, dissent in the RG's ranks?

I would like to know why a building was named for Dunn in the first place.  Despite the negative editorial today, at some point in the past, important people respected Dunn enough to name a building after him.  Why?  Come on RG in dissing a man like this it is important to tell the whole story.  People at the time thought he did something good.  What was that good?  I should be pissed as a member of the Catholic tradition about Dunn, but I am not because it is part of dead history.  I am more concerned about what he did that was good than his failings as measured by today's PC culture.
