I haven't been over to UMASS Lowell's North Campus lately to check out if there was any evidence of a plaque in the memory of Mahlon Webb Dennett, WW1 soldier who lost his life in France. Thank goodness for the world wide web. Wikimedia has a photo of a plaque on North Campus! I'm not sure exactly where it is but it should be near Cumnock Hall.
Wikimedia has photos that are in the public domain. So thank you Daderot whoever you are!!
