With his move from Menlo Park, New Jersey, to New York City at the end of March 1881, Edison shifted his focus from research and development to the commercialization of his electric lighting system. The newest volume of The Papers of Thomas A. Edison chronicles Edison’s central role in the enormous effort to manufacture, market, and install electric lighting systems in the United States and abroad. Standard studies of this period emphasize the inauguration of the commercial electric utility industry at the Pearl Street central station. Edison and his associates, however, audaciously operated on a global scale, not just focusing on the major cities of North America and Europe but reaching simultaneously from Appleton, Wisconsin, to Australia, through the Indian subcontinent and East Asia, to Central and South America.
