Crocker and I maintained that there is an electrical science which is the real soul of electrical engineering, and that every other abstract science or its application was an incident only in electrical engineering. We won out in spite of the fact that at other institutions of higher learning in the United States electrical engineering was taught in the departments of physics or of mechanical engineering. But it was not an easy matter in those days to persuade people that the electrical science with its applications was then, or that it ever would be, big enough to need a department of its own, like, for instance, civil engineering. A small brick shed, a temporary structure, had been built at Columbia College to accommodate the new department. The students called it the “cowshed,” and the boy who invented the name did not indulge in any stretching of his imagination. It certainly looked like a cowshed. The laboratory equipment consisted of a dynamo, a motor, and an alternator, with some so-called practical measuring instruments. When I compared the facilities of the new “Department of Electrical Engineering at Columbia College” with that of the Polytechnic School in Berlin, I felt somewhat humbled, but not discouraged. I said to Crocker: “Our guns are small and few in number; the men behind the guns will have to expand much beyond their present size if this department is to make any impression upon the electrical art.” “Pupin,” said Crocker, “you have no idea how rapidly a young fellow grows when he tries to teach a new subject to poorly prepared beginners.”
