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.
U.S. patent 341,212 Reproducing Sounds from Phonograph Records (without using a stylus or causing wear), filed November 1885, issued May 1886 (with Alexander Bell and Charles Tainter) U.S. patent 341,213 Transmitting And Recording Sounds By Radiant Energy, filed November 1885, issued May 1886 (with Alexander Bell and Charles Tainter)
The basic distinction between the Edison's first phonograph patent, and the Bell and [Charles Sumner] Tainter patent of 1886 was the method of recording. Edison's method was to indent the sound waves on a piece of tinfoil, while Bell and Tainter's invention called for cutting, or 'engraving', the sound waves into a wax record with a sharp ...
Subsequent to the issuance of the Bell and Tainter patent No. 341214, Edison announced that he would shortly produce his 'new phonograph' which, when it appeared, was in fact nothing but the Bell and Tainter record set forth in their patent 341214, being a record cut or engraved in wax or wax-like material, although Edison always insisted on ...

A coin-operated version of the Graphophone, U.S. patent 506,348, was developed by Tainter in 1893 to compete with nickel-in-the-slot entertainment phonograph U.S. patent 428,750 demonstrated in 1889 by Louis T. Glass, manager of the Pacific Phonograph Company.
The North American Phonograph Company was an early attempt to commercialize the maturing technologies of sound recording in the late 1880s and early 1890s. Though the company was largely unsuccessful in its goals due to legal, technical and financial problems, it set the stage for the modern recording industry in the mid 1890s.
A photophone receiver and headset, one half of Bell and Tainter's optical telecommunication system of 1880. The photophone was similar to a contemporary telephone, except that it used modulated light as a means of wireless transmission while the telephone relied on modulated electricity carried over a conductive wire circuit.
