Thomas Edison and the Practical Electric Light
Thomas Alva Edison was born on 11 February 1847 in Milan, Ohio, USA. He was the youngest of  at homesoldhourslight bulblaboratorybrieflyexperimentspatentsoperatorsevenpatiencelonger-lasting children.

A light bulb was useful only if homes and streets had electricity. Therefore, Edison also developed generators, wires, switches and an electricity distribution system. In 1882, the Pearl Street power station began supplying electricity to customers in New York City. Edison also worked on the phonograph, motion-picture technology and improved telegraph systems.
