Stephen D. Field ( -1913)
1914 Obituary 
STEPHEN D. FIELD died at his residence in Stockbridge, Massachussetts, U.S.A., the 18th May, 1913.
He was an inventor in many branches of electrical work, including telegraphy, and in 1879-1880 applied for patents for an electric railway, comprising a stationary generator, a trolley wire, an electric car, an under-running trolley, and bonded rails for the return circuit.
In the latter year he constructed an experimental electric line in Stockbridge, and in 1883, in connection with Mr. Edison, operated an electric locomotive by a third-rail at the Chicago Railway Exposition.
After his early work he paid little attention to electric railways, except in the later nineties, when, representing American capitalists, he had charge of the electrical equipment of the tramway system at Geneva, Switzerland.
He was elected a Member of the Institution in 1877.
