Thomas Alva Edison was an American inventor and businessman who has been described as America's greatest inventor. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory.
William Kennedy-Laurie Dickson was a Scottish inventor who devised an early motion picture camera under the employment of Thomas Edison.
Execution by electrocution, performed using an electric chair, is a method of execution originating in the United States in which the condemned person is strapped to a specially built wooden chair and electrocuted through electrodes fastened on the head and leg. This execution method, conceived in 1881 by a Buffalo, New York, dentist named Alfred P. Southwick, was developed throughout the 1880s as a supposed humane alternative to hanging, and first used in 1890. This execution method has been used in the United States and for several decades in the Philippines. While death was originally theorized to result from damage to the brain, it was eventually shown in 1899 that it primarily results from ventricular fibrillation and eventual cardiac arrest.
Edison is a township located in Middlesex County, New Jersey, United States. Situated in central New Jersey, Edison lies within the core of the state's Raritan Valley region and is part of the New York City metropolitan area. Home to Little India, as of the 2010 United States Census, Edison had a total population of 99,967, retaining its position as the fifth-most populous municipality in New Jersey. The 2010 population reflected an increase of 2,280 (+2.3%) from the 97,687 counted in the 2000 Census, which had in turn increased by 9,007 (+10.2%) from the 88,680 counted in 1990. Edison's population surpassed the 100,000 threshold since 2010, increasing by 0.7% to a Census-estimated 100,693 in 2018 before dipping back to 99,758 in 2019.
The war of the currents, sometimes called battle of the currents, was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting being marketed by Thomas Edison's company. In 1886, the Edison system was faced with new competition: an alternating current system developed by George Westinghouse's company that used transformers to step down from a high voltage so AC could be used for indoor lighting. Using high voltage allowed an AC system to transmit power over longer distances from more efficient large central generating stations. As the use of AC spread rapidly, the Edison Electric Light Company claimed in early 1888 that high voltages used in an alternating current system were hazardous, and that the design was inferior to, and infringed on the patents behind, their direct current system.

Frank Julian Sprague was an American naval officer and inventor who contributed to the development of the electric motor, electric railways, and electric elevators. His contributions were especially important in promoting urban development by increasing the size cities could reasonably attain and by allowing greater concentration of business in commercial sections. He became known as the "Father of Electric Traction". He demonstrated an aptitude for science and mathematics, Sprague secured an appointment to the U.S. Naval Academy in 1874. He pursued his electrical studies relentlessly after graduation in 1878 and 2 years at sea.

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.
