Telephone inventor Alexander Graham Bell related to his father in a letter dated March 10, 1876, that “articulate speech was transmitted intelligibly this afternoon” from a “transmitter instrument” in one room to a “receiving instrument in another room.” Bell Telephone Company introduced the battery-transmitting telephone two decades later, on December 20, 1898.
