Great White WayIn 1880, New York's Broadway was first lighted by electricity and became known as the “Great White Way.” Charles F. Brush successfully demonstrated his arc lamps along Broadway. His arc lights preceded Edison's incandescent light bulb in commercial use. Arc lights were suited to applications where a bright light was needed, such as street lights and lighting in commercial and public buildings.[Image: detail from the cover of the Scientific American issue of 2 Apr 1881.] |
