GEORGE WESTINGHOUSE the man may be overshadowed by his inventions, company, or legend. But in this biography by Henry G. Prout, Westinghouse’s personal life and history are recounted along with his many inventions and enterprises – and his inventions and enterprises were enormous. He dealt in the same week, and often in the same day, with organization, financial and executive affairs, commercial affairs, and the engineering details of half a dozen companies in two hemispheres, Prout noted. They were as far apart in kind as the air brake and natural gas, and as far apart in geography as San Francisco and St. Petersburg. This biography covers topics as diverse as power signaling and switching, Westinghouse’s use of the alternating current, his activities at Niagara Falls, his European enterprises, his financial methods, and his overall impact on rail transportation and the power industry.
