William Stanley, Jr. (November 28, 1858–May 14, 1916) was an American physicist born in Brooklyn, New York. In his career, he obtained 129 patents covering a variety of electric devices.
Stanley was as an electrician working with telegraph keys and fire alarms of an early manufacturer. In New York, Stanley designed one of the first electrical installations (at a Fifth Avenue store). Shortly there after, George Westinghouse hired Stanley as his chief engineer at his Pittsburgh factory.
In 1885, Stanley built the first practical alternating current device based on Lucien Gaulard and John Dixon Gibbs' idea. This device was called an induction coil. It was the precursor to the modern transformer. The induction coil that Stanley built was very primitive. Stanley's work led him to be hired by George Westinghouse as his chief engineer in Pittsburgh.
