While Tesla probably contributed far more to the electrical industry than any other two people put together, he did not invent it. Westinghouse did not invent it, either. But it was his company, with Tesla working for him, that made AC the standard in the U.S. Westinghouse opened the first AC transformer system in 1886. Tesla’s company opened in 1887. They started working together in 1888. The ISBN number of the book I’m referencing is 0-88029-419, page 38.
