Thomas Edison National Historical Park

Thomas Edison National Historical Park preserves Thomas Edison's laboratory and residence, Glenmont, in West Orange, New Jersey, United States. These were designed, in 1887, by architect Henry Hudson Holly. The Edison laboratories operated for more than 40 years. Out of the West Orange laboratories came the motion picture camera, improved phonographs, sound recordings, silent and sound movies and the nickel-iron alkaline electric storage battery.
