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.
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. [8]

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.

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.
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound.Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to their disc-shaped successor, these hollow cylindrical objects have an audio recording engraved on the outside surface which can ...
Bell and Tainter's Photophone receiver, one part of the device to conduct optical telephony. The Photophone, also known as a radiophone, was invented jointly by Bell and his then-assistant Sumner Tainter on February 19, 1880, at Bell's 1325 'L' Street laboratory in Washington, D.C. [8] [30] Bell believed the photophone was his most important ...
