George W. Hilton, 1925-2014. Professor Hilton, co-author with John Due of The Electric Interurban Railways in America, was the first and so far only honorary Life Member of the Central Electric Railfans Association. His academic work contributed to the revival of the freight railroads. Trains notes, "He practically identified himself with competitive organization of the railroads and prided himself on his contribution to the abolition of the Interstate Commerce Commission." Professor Hilton was less favorably disposed toward much of the Passenger Rail enterprise, that despite having great regard for underdog carriers such as Monon and Erie. We shall miss his work.
Economics footnote: that's the same John Due who worked with Robert Clower on Microeconomics.
