Apparatus for Recording and Reproducing Sounds
Charles Tainter invented various sound-recording instruments, including an improved version of Thomas Edisonís phonograph known as the Graphophone, the Photophone, and the Dictaphone.
Born in Watertown, Massachusetts, Tainter, a self-educated man, began working for electrical and optical instrument companies in Boston, Massachusetts in 1870. His experience led him to establish his own business, where he worked with Alexander Graham Bell making electrical devices. After Tainter contributed to Bellís first transmission of sound, the duo created the radiophone, an instrument that used light waves and selenium cells to transmit wireless sound.
