Biographical / Historical
William Stanley Jr. (1858-1916) was an inventor and engineer who held 129 patents. He is responsible for pioneering the development and use of alternating current for electric light and power. Born in Brooklyn, New York, he attended private schools before enrolling at Yale University. He began to study law at age 21 but left school to look for a job in the emerging field of electricity. While in New York, he was employed in various roles before accepting a post with Edison rival, Hiram Maxim. In 1884, he went into a business venture with George Westinghouse of the Westinghouse Electrical Company in Pittsburgh which would prove tumultuous. Suffering from tuberculosis, he moved back to Great Barrington, Massachusetts for his health. Here he rented out a rubber factory to continue electrical experiments, of which, he considered outside of his scope of work for Westinghouse. In 1885, he developed the first practical transformer which spurred the development of AC power. The transformer design became the prototype for all future transformers, and his AC distribution system formed the basis of modern electrical power distribution. In 1890, Stanley joined with John Kelley and Cummings C. Chesney to form the Stanley Manufacturing Company in Pittsfield, Massachusetts with the purpose of manufacturing electrical products. The company quickly developed all components required to make an electrical system including the alternator, transformer, motor, watt-hour meter, and lights. Their products were sold as part of an S.K.C. system. The business was purchased by General Electric in 1903. His other inventions include the thermos bottle. Stanley died prematurely of tuberculosis in 1916.
