This Appleton, Wisconsin, home was the first in the United States to be lit via hydroelectric power sourced from the Appleton Edison Light Company. Built in 1882 by businessman Henry James Rogers for his wife, this Queen Anne Victorian may be the only surviving example of wiring and fixtures in their original location from the early days of the electrical age. If you visit the museum between November and January, you'll see the house all decked out for the holidays.
