A new Hollywood movie opened over the weekend, called "The Current War." The movie tells the dramatic story of the cutthroat race between electricity titans Thomas Edison and George Westinghouse to determine whose electrical system would power the modern world.
The invention of the incandescent light bulb had an enormous effect on American society and historian Ernest Freeberg of the University of Tennessee wrote a book about it called "The Age of Edison: Electric Light and the Invention of Modern America."
He explores how and why the light bulb changed nearly everything about American life, economy, society, architecture, sports, entertainment and health.
Ernest Freeberg spoke at the Minnesota Historical Society’s “History Forum” on Feb. 14, 2015.
