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.
While cylinder phonographs never employed the lateral cutting process commercially, this later became the primary method of phonograph disc recording. Bell and Tainter also developed wax-coated cardboard cylinders for their record cylinder.
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 Tainter patent of 1886 was the method of recording. Edison's method was to indent the sound waves on a piece of tin foil, while Bell and Tainter's invention called for cutting, or "engraving", the sound waves into a wax record with a sharp recording stylus.

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 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.
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 ...
The Volta Laboratory was established by Alexander Graham Bell in Washington, D.C. in 1881. When the Laboratory's sound-recording inventions were sufficiently developed with the assistance of Charles Sumner Tainter and others, Bell and his associates set up the Volta Graphophone Company, which later merged with the American Graphophone Company (founded in 1887) which itself later evolved into ...
