Le Téléphone, le Microphone et le Phonographe

This lively illustrated volume turns the listener’s ear toward the surprisingly long road that led from simple acoustic tricks to the devices that changed how we speak across continents. Beginning with ancient Greek whispers and the daring experiments of Robert Hooke in the 1660s, it follows a chain of curious inventors who stretched strings, wooden rods, and taut membranes to carry a voice over a hundred metres. The narrative weaves together vivid woodcut drawings and clear explanations, showing how a child's toy‑like fiddle‑phone became a stepping‑stone for serious scientific inquiry.

The second part picks up in the nineteenth century, when electricity promised to carry speech faster than any cord could. Readers meet the likes of Wheatstone, Bourseul, and early American experimenters who imagined magnetic vibrations as a new language of sound. By examining laboratory sketches and contemporary reports, the book reveals how each breakthrough—though often dismissed as fantasy at the time—laid the groundwork for the telephone, microphone, and phonograph that would soon reshape daily life.
