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, Edison Storage Battery Company and Emark Battery Corporation. , president of the company 1927–57 In the 1920s the recording company began to lag in technical innovation, and also failed to attract recording stars of the same quality as its rivals Victor and Columbia. An attempt to market a long playing record in 1926 did not succeed, and the company did not begin recording electrically until mid-1927, two years after the rest of the industry had adopted the process. In 1928 the company finally moved into radio with the purchase of the Splitdorf Radio Corp. On 1 November 1929 Edison halted production of records apart from dictation records made by the Voicewriter division. In the late 1920s the "Edicraft" line of high-quality consumer appliances was developed at the laboratory and manufactured by Thomas A. Edison, Inc. Production of appliances was discontinued in 1934 due to lack of demand for luxury goods during the Great Depression.
Merger
, founder and president of McGraw Electric, had always been an admirer of Thomas Alva Edison, and had his picture hanging in his office. In 1956 he arranged a meeting with his son Charles Edison, former Governor of New Jersey and Secretary of the Navy, to discuss merging their two companies. They spent a few days at the Broadmoor resort in Colorado Springs, Colorado and came to an agreement. The merger was effective 2 January 1957. The combined company was named the McGraw-Edison Company. Max McGraw would joke after the merger that his name now appeared before Edison's on the New York Stock Exchange.
