The Norman Thomas High School in Manhattan and the Norman Thomas ‘05 Library at Princeton University’s Forbes college are named after him. He was also the grandfather of Newsweek columnist Evan Thomas. None of this should come as any surprise considering the locations and leanings of those institutions and people.
The discussions of Fabiansim and Mr. Thomas history are fine, what I need to know is not if he “might or could” have made that quote. But DID he.
