Bill Cronon is definitely one of the last historians at UW-Madison (where I went to grad school) that I would think of as a radical or even as very political. Even his masterwork, Nature?s Metropolis, which I happen to be assigning this semester in my 19th century America class, is marred by an inattention to politics (though still a very fine book, a real model of the craft in many other respects).
