Content: To prove that the device could transmit acoustic sounds over long distances, Reis sent a hard-to-understand German phrase ‘Das Pferd frisst keinen Gurkensalat’ (The horse does not eat cucumber salad). A British telephone company named Standard Telephones and Cables later found that Reis’ device built in the early 1860s were capable of transmitting and reproducing speech of good quality, but of low efficiency. Philip Reis died in 1874, and four years later, European researchers dedicated a monument to him as the inventor of the telephone. Innocenzo Manzetti
Reported to have invented a speaking-telegraph in 1864
Innocenzo Manzetti first presented the idea of a ‘speaking telegraph’ in 1843. However, he did not come up with any working prototype until 1864. In 1865, he constructed an electrical telephone that could reproduce loudly spoken vowels and music with good quality. However, it was neither patented nor presented at any conference by Manzetti himself. Although the Parisian newspaper, Le Petit Journal, described the device in a brief article , there were no historical records of British companies implementing Manzetti’s telephone in any region, in that time period. Elisha Gray
Designed a telephone using a water microphone in 1876
Elisha Gray was an American electrical engineer. He was best known for developing a telephone prototype that used a metal rod dipped into an acid mixture (or any other liquid conductor).
