Caption: Edison's telephonography. 19th-century illustration of the telephonography system developed by US inventor Thomas Alva Edison (1847-1931). This early form of telephony, using the Edison phonograph at each end, is here being operated by Edison's laboratory assistant William Joseph Hammer (1858-1934). It is being used to transmit speech from New York to Philadelphia, over a distance of 165 kilometres. The speech is being transmitted to a speaker and played to an audience at lower right. The telephone was developed in the 1870s, with several inventors pioneering the technology. This illustration is from 'Physique Populaire' (Emile Desbeaux, 1891).
