Edison, Incorporated (originally the National Phonograph Company) was the main holding company for the various manufacturing companies established by the inventor and entrepreneur Thomas Edison. It was a successor to Edison Manufacturing Company and operated between 1911 and 1957, when it merged with McGraw Electric to form McGraw-Edison. The National Phonograph Company was incorporated on 27 January 1896. It was restructured and reincorporated as Thomas A. Edison, Inc. on 28 February 1911. Edison Manufacturing Company also became a division of Thomas A. Edison, Inc. at this time. The company had an industrial research laboratory in West Orange, New Jersey where up to 200 people were employed in the "rapid and cheap development of inventions." Frank L. Dyer was president until December 1912, when Thomas Edison took over the position himself. C.H. Wilson, general manager, was also vice president from 1912. Edison resigned as president in August 1926 in favor of his son, Charles Edison, and became chairman of the board. The company had divisions handling different products such as phonographs, Ediphone, and storage batteries. One of the first products were Blue Amberol cylinders and the Amberola player, an early sound recording medium and player. This was followed by the Edison Diamond Disc. In 1915 the soprano Anna Case and contralto Christine Miller showed in a tone test at the West Orange lab that there was no difference between their live voices and Diamond Disc recordings of their voices. Other Edison companies were absorbed in the years that followed, including Edison Phonograph Works (28 August 1924), Edison Storage Battery Company (30 June 1932) and Emark Battery Corpora Item ordered may not be exact piece shown.
