George Westinghouse was an amazing American who changed the world. He invented the air brake for trains. Until this invention, only locomotives had brakes and thousands died annually in train wrecks. Every train in the world today still uses his system. In addition, the AC power used all over the world was pioneered by Westinghouse. Edison wanted to use DC power because he could make more money but Nikolai Tesla convinced Westinghouse that AC was better . His impact on the world was huge.
George Westinghouse-Edison got most of the credit, it’s hard to argue that Westinghouse’s contributions were almost as great as Edison’s. Certainly it was his electrical system, which used alternating current based (a result of the work of Nikola Tesla, by the way), that ultimately prevailed over Edison’s insistence on direct current and paved the way for the modern power grid. Westinghouse invented the railway air brake, which did much to improve the safety of the American railway system.
In what is considered the first industrial use of alternating current in 1891, workmen pose with a Westinghouse alternator at the Ames Hydroelectric Generating Plant. This alternator was used as a generator producing 3000 volt, 133 Hertz, single-phase AC.
Inventor George Westinghouse,though born in New York, made his fortune in Pittsburgh. Backed Tesla's AC electrical current as superior to Edison's DC current. Recognized Tesla's as superior because he knew a good invention when he saw one. Discovered the airbrake among many of his own innovations. Lived in Homestead and worked at his castle in Wilmerding, formerly the Westinghouse Museum. Remember, "You can be sure if it's Westinghouse."
