Thomas A. Edison had invented the phonograph in 1877, but the fame bestowed on him for this invention — sometimes called his most original — was not due to its efficiency. Recording with his tinfoil phonograph was too difficult to be practical, as the tinfoil tore easily, and even when the stylus was properly adjusted.
Charles Sumner Tainter (April 25, 1854 – April 20, 1940) was an American scientific instrument maker, engineer and inventor, best known for his collaborations with Alexander Graham Bell, Chichester Bell, Alexander's father-in-law Gardiner Hubbard, and for his significant improvements to Thomas Edison's phonograph, resulting in the Graphophone, one version of which was the first Dictaphone.
Edison in 1861. Thomas Edison was born in 1847 in Milan, Ohio, but grew up in Port Huron, Michigan, after the family moved there in 1854. [8] He was the seventh and last child of Samuel Ogden Edison Jr. (1804–1896, born in Marshalltown, Nova Scotia) and Nancy Matthews Elliott (1810–1871, born in Chenango County, New York).
Thomas Edison's phonograph becomes the first device to record and reproduce sound. The method is fragile, however, and is prone to damage. [2] 1879: Invention: Thomas Edison invents the first dictation machine, a slightly improved version of his phonograph. [2] 1936: Invention
This material described in detail the strange creations and even stranger experiments at the laboratory which led to the greatly improved phonographs in 1886 that were to help found the recording and dictation machine industries. [24] [25] Thomas A. Edison had invented the phonograph in 1877. But the fame bestowed on Edison for this invention ...

Edison Dictation Phonograph, 1893. Through 1893, North American, under Edison, continued to sell Phonographs, and offered the option to buy the machines on the installment plan. Edison planned to carry on with the business in this way for another year (from June 1893), then planned to consolidate his interests in manufacture and sales. [6]
It took five years of research under the directorship of Benjamin Hulme, Harvey Christmas, Charles Sumner Tainter and Chichester Bell at the Volta Laboratory to develop and distinguish their machine from Thomas Edison's Phonograph. Among their innovations, the researchers experimented with lateral recording techniques as early as 1881.
