First Public Demonstration of Edison's Light Bulb
December 31, 1879
Can you imagine what life was like before you could simply flip a switch and turn on a light? How would not having electric light affect the way you live your life? In the 1870s, many inventors were working on creating lighting devices, but until Edison became involved, what existed was electric arc lighting. This kind of lighting system was one in which lights were connected in a series circuit, so if one failed, the whole circuit failed. Edison boasted that he would create a safe, reliable, and inexpensive electric light that would replace gaslight.
