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.
Some models, like the Type G, had new upper-works that were not designed to play Bell and Tainter cylinders. The name Graphophone was used by Columbia (for disc machines) into the 1920s or 1930s, and the similar name Grafonola was used to denote internal horn machines.
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.

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)
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.
As the automatic exhibition model gained ground, American Graphophone's dictation-optimized format (colloquially 'Bell-Tainter cylinders' today) fell suddenly behind. Lippincott's initial agreement with American Graphophone committed North American to buy 5,000 graphophones each year, and pay a royalty of $20 on each.
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 ...
