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.
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.

Although Bell Telephone researchers made several modest incremental improvements on Bell and Tainter's design, Marconi's radio transmissions started to far surpass the maximum range of the photophone as early as 1897 [8] and further development of the photophone was largely arrested until German-Austrian experiments began at the turn of the ...

[8] [30] Bell believed the photophone was his most important ...
