Edison said his favorite movie was The Birth of a Nation. "They were proud of her--for she had been one of their own rank in the, shop and yet remained as gracious and friendly to them as ever."

Their fortunes fluctuated with their politics. [46] His work was concurrent with Emile Berliner's loose-contact carbon transmitter (who lost a later patent case against Edison over the carbon transmitter's invention[47]) and David Edward Hughes study and published paper on the physics of loose-contact carbon transmitters (work that Hughes did not bother to patent).[46][48]. For other uses, see. Eight months earlier in January 1882, to demonstrate feasibility, Edison had switched on the 93 kW first steam-generating power station at Holborn Viaduct in London. It is the oldest award in the area of electrical and electronics engineering, and is presented annually "for a career of meritorious achievement in electrical science, electrical engineering or the electrical arts". Edison did not demonstrate a mature product until 1910: a very efficient and durable nickel-iron-battery with lye as the electrolyte. "[138], Edison was a supporter of women's suffrage. [73] Primary was the fact that Edison Electric based their design on low voltage DC and switching a standard after they had installed over 100 systems was, in Edison's mind, out of the question. Edison is credited with designing and producing the first commercially available fluoroscope, a machine that uses X-rays to take radiographs. These early bulbs all had flaws such as an extremely short life and requiring a high electric current to operate which made them difficult to apply on a large scale commercially.
