Caption: Ader telephone station. 19th-century illustration of the wiring and apparatus used for a telephone station, as developed by French engineer Clement Ader (1841-1925). The design includes a transmitter (pad at centre), two receivers (earphones on hooks at left and right), batteries (lower centre), and an electric bell (top centre). The telephone was developed in the 1870s, with several inventors pioneering the technology. This illustration is from 'Physique Populaire' (Emile Desbeaux, 1891).
