Who would have thought, forty years ago, that the lighting of these dark and dirty streets and the modernization of these local railway systems would have given rise to one of the most astounding chapters in our financial history and created hundreds, perhaps thousands, of millionaires? When Thomas A. Edison invented the incandescent light, and when Frank J. Sprague in 1887 constructed the first practicable urban trolley line, in Richmond, Virginia, they liberated forces that powerfully affected not only our social and economic life but our political institutions. These two inventions introduced anew phrase--"Public Utilities." Combined with the great growth and prosperity of the cities they furnished a fruitful opportunity to several particularly famous groups of financial adventurers. They led to the organization of "syndicates" which devoted all their energies, for a quarter of a century, to exploiting city lighting and transportation systems. These syndicates made a business of entering city after city, purchasing the scattered street railway lines and lighting companies, equipping them with electricity, combining them into unified systems, organizing large corporations, and floating huge issues of securities. A single group of six men--Yerkes, Widener, Elkins, Dolan, Whitney, and Ryan--combined the street railways, and in many cases the lighting companies, of New York, Philadelphia, Chicago, Pittsburgh, and at least a hundred towns and cities in Pennsylvania, Connecticut, Rhode Island, Massachusetts, Ohio, Indiana, New Hampshire, and Maine. Either jointly or separately they controlled the gas and electric lighting companies of Philadelphia, Reading, Harrisburg, Atlanta, Vicksburg, St. Augustine, Minneapolis, Omaha, Des Moines, Kansas City, Sioux City, Syracuse, and about seventy other communities. A single corporation developed nearly all the trolley lines and lighting companies of New Jersey; another controlled similar utilities in San Francisco and other cities on the Pacific Coast. In practically all instances these syndicates adopted precisely the same plan of operation. In so far as their activities resulted in cheap, comfortable, rapid, and comprehensive transit systems and low-priced illumination, their activities greatly benefited the public. The future historian of American society will probably attribute enormous influence to the trolley car in linking urban community with urban community, in extending the radius of the modern city, in freeing urban workers from the demoralizing influences of the tenement, in offering the poorer classes comfortable homes in the surrounding country, and in extending general enlightenment by bringing about a closer human intercourse. Indeed, there is probably no single influence that has contributed so much to the pleasure and comfort of the masses as the trolley car.
