These rather nicely done paintings celebrating the "Westinghouse Centenary" appeared in a 1946 issue of Popular Science magazine. The centenary marked the 100th year since the birth of George Westinghouse, not the company. We electrical and electronics types know Westinghouse Electric Corporation, founded by George Westinghouse in 1886, as a company that makes electrical distribution equipment, electronics products and systems (e.g., radar, microwave transmission), household appliances, industrial motors and generators, jet engines, and other high tech products. However, George Westinghouse was famous first for his locomotive air brake design. He teamed up with Nikola Tesla to battle Thomas Edison over the superiority of alternating current (AC) over direct current (DC) for building a large scale distribution system. The caption of one picture mentions that DC systems could only cover 16 square miles (~4 mi. x 4 mi.). Line losses due to high currents dissipated a large part of the power. AC allowed voltages to be cranked way up to keep current down. Unlike DC, AC can be efficiently and economically transformed up and down. However, modern principles are allowing high voltage direct current (HVDC) to be implemented from generation plants to AC substations. One advantage of DC is not needing to phase-synchronize the system.

Westinghouse Centenary

High spots in the long inventive career of George Westinghouse are recreated in these paintings, which are based on meticulous historical research.

In 1885, direct-current stations served only 16 square miles. Westinghouse found how to extend area by A. C.

"Mary Ann," 2,000-kw. steam-turbine generator, was the first unit of the kind to be installed in U. S.

First air-brake train stops short just in the nick of time and convinces witnesses of its quick efficiency.

Big night in Great Barrington, Mass., was when Westinghouse proved that town could be lighted with A. C.
