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.

Nikola Tesla emigrated to the US in 1884 to work for Thomas Edison. He soon struck out on his own with financial backers. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric power development was involved in a corporate alternating current/direct current "War of Currents" as well as various patent battles.

Nikola Tesla and George Westinghouse - With the big money supporting DC currents (Edison Electric, J.P. Morgan, Thomson-Houston Company - through a merger into G.E. General Electric), Pittsburgh magnate George Westinghouse stood by Tesla's AC current, because as an inventor himself, he knew that the technology was superior, and felt that it would eventually win the war of the currents. Tesla, amazingly, would later give up his $2.50 per horsepower of electrical capacity sold that he was due.

Nikola Tesla the greatest geek who ever lived. Over a 100 years ago, a Serbian-American inventor (Nikola Tesla) started fixing things that weren't broken. In a time when the majority of the world was still lit by candles, an electrical system known as alternating current was invented and to this day is what powers every home on the planet. We have Nikola to thank for that!
