Approximately 70% of people may not be familiar with the historical context of early telephones. However, let’s delve into some key milestones in the development of telecommunication technology to shed light on this fascinating journey:
In 1844, Innocenzo Manzetti introduced the concept of a “speaking telegraph” or telephone. Initially, these devices were referred to as “speaking telegraph” and “sound telegraph,” but eventually, the term “telephone” emerged as the standard name.
On August 26, 1854, Charles Bourseul published an article in the magazine L’Illustration (Paris) titled “Transmission électrique de la parole” (electric transmission of speech), outlining a “make-and-break” type telephone transmitter that would later be recreated by Johann Reis.
On October 26, 1861, Johann Philipp Reis publicly demonstrated the Reis telephone before the Physical Society of Frankfurt. His telephone was not limited to transmitting musical sounds; he also used it to convey the phrase “Das Pferd frisst keinen Gurkensalat” (“The horse does not eat cucumber salad”).
Furthermore, on August 22, 1865, La Feuille d’Aoste reported that English technicians, after being introduced to Manzetti’s method for transmitting spoken words on telegraph wires, were considering applying this invention in England on several private telegraph lines.
This historical information serves as a testament to the early developments in telephone technology and the individuals who contributed to its evolution. It’s a fascinating journey that ultimately led to the telephone as we know it today.
