AT A GLANCE:
The modern world is an electrified world. The light bulb, in particular, profoundly changed human existence by illuminating the night and making it hospitable to a wide range of human activity. The electric light, one of the everyday conveniences that most affects our lives, was invented in 1879 by Thomas Alva Edison. He put together what he knew about electricity with what he knew about gas lights and invented a whole of electrical system.
