The Incandescent Light Bulb



1878: Edison creates his prototype incandescent light bulb: a thin strip of paper, attached to wires, enclosed in a vacuum inside a glass bulb. When electricity flowed into the paper "filament," it heated up, and glowed.

1882: Edison and partners form the Edison Electric Illuminating Company of New York, bringing electric light to parts of Manhattan. But progress was slow. Most American will still light their homes with gas light and candles for another fifty years. In 1925, only half of all homes in the U.S. will have electric power.

How the Incandescent Light Bulb and Electricity Transform a Frontier Town

In the late 19th century, electrification was transforming American cities. Electricity, along with railroads and the telegraph, were reshaping the American landscape. Contemporaries saw these as emblematic of intellectualism, nationalism, and civilization. These were the symbols of American progress, destiny made manifest. John Gast popularized attitudes in his 1863 painting American Progress, where Columbia advances west, flanked by the railroad, a coil of telegraph wire over one arm, and bringing light from the east behind her.
