Fayerweather Hall
Fayerweather Hall is an old building that hasn't been renovated in decades. Its vintage interiors, which look and feel exactly like what you'd expect an old Ivy League school academic building to look and feel like, holds captive the History and Sociology Departments. Walking around the sixth floor and looking at the nameplates of world famous historians on office doors is enough to leave most history students awestruck.
It was named after Daniel B. Fayerweather, a wealthy shoe manufacturer who had no connection whatsoever to Columbia, but decided to give a few hundred thousand dollars anyway.
During the 1968 protests Fayerweather was occupied by students. They even held a wedding during the course of the occupation.
Interestingly enough, the building originally housed the Physics Department before it moved into bigger digs in Pupin Physics Laboratories.
