The "Jumbo" Dynamo in Its Original Setting, Edison's Pearl Street Lighting Station, New York, New York, circa 1890

Edison's successful lighting experiments at his Menlo Park laboratory in 1879 bore fruit in the practical system he put into operation in New York City, at the center of which was the Pearl Street power station. This was the first engine-generator to go online providing power to customers on September 4th, 1882. The sole surviving engine-generator from that installation, it is now displayed at Greenfield Village in Dearborn, Michigan.
