It was still there when I was going to the campus in the seventies. in fact, we had the student government and newspaper office in the mansion. It was pretty beat up and would've taken a lot of $$ to bring it up to code.
The big problem was that they couldn't get it on any landmark lists to tap into funds. Nobody outside of DuBois was that interested in the historical angle, and the building was not a real example of the architectural style. It was fake tudor, so nobody bit on that basis either.
