Come and meet the men behind the history of telecommunications.

Les pères fondateurs de la société de communication

Claude CHAPPE (1763-1805): from semaphore to the beginnings of the network

A passionate physicist, he designed a network which prefigured modern telecommunications: the optical telegraph.

SAMUEL MORSE (1791-1872): THE BIRTH OF MODERN TELECOMMUNICATIONS

Morse code enabled electrical telegraphy to become a truly effective technology.

THOMAS EDISON (1847 – 1931): RECORDING AND LISTENING TO SOUND

From electricity to telephony, by way of cinema, this brilliant inventor developed a device which could record sound, which he called the phonograph.

GEORGE EASTMAN (1854-1932): PHOTOGRAPHY FOR ALL

By developing flexible film and using it in a simple and relatively compact device, the American George Eastman laid the foundations for a system he would develop and market under the KODAK brand.

THE LUMIÈRE BROTHERS (1862-1948) AND THE CINEMA

The cinematography developed by the Lumière brothers enabled both the recording and projection of moving images.

HERMANN HOLLERITH (1860-1929): AUTOMATED INFORMATION MANAGEMENT

For the 1890 census, the American government used the statistics machine developed by Hermann Hollerith. The Tabulating Machine Co. was founded shortly afterwards. This company would later become IBM and dominate the global computer industry until the 1980s.

GUGLIELMO MARCONI (1874-1937) AND WIRELESS TELEGRAPHY

Marconi synthesized the work of various researchers, including the German Hertz, the Frenchman Branly and the Russian Popov, to make the first radio transmission (in Morse code).

LEE DE FOREST (1873-1961): THE BIRTH OF ELECTRONICS

The American Lee de Forest developed the triode valve. This invention enabled, as early as 1915, the first telephone link between New York and San Francisco.

ALEXANDER GRAHAM BELL (1847-1922): INVENTOR OF THE TELEPHONE

Bell invented the telephone in 1876, and it was while working on various experiments related to the problem of deafness that he began to focus on research into remote voice transmission.
