The 1932 Niagara Mohawk Building in Syracuse, New York -- the classic art deco headquarters of the nation's largest utility company. According to the National Park Service, its architecture "expressed the technology of electricity through its modernistic design, material, and extraordinary program of exterior lighting. . . . architects Melvin L. King and Bley & Lyman transformed a corporate office tower into a widely admired beacon of light and belief in the future." Photo by Carol Highsmith, 2018.
