Telecommunication
The conventional telephone was invented independently by Alexander Bell and Elisha Gray in 1876. Antonio Meucci invented the first device that allowed the electrical transmission of voice over a line in 1849. However Meucci's device was of little practical value because it relied upon the electrophonic effect and thus required users to place the receiver in their mouth to "hear" what was being said. The first commercial telephone services were set-up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London.
Culture of Italy
At the start of the 20th century, Guglielmo Marconi carried out experiments in electricity and developed the wireless, but he was preceded by Count Alessandro Volta, one of the pioneers of electricity, over 100 years earlier. By the end of the Second World War, Enrico Fermi's work in nuclear physics led to the development of both the atomic bomb and peaceful atomic applications. On 25 September 2001, US Congress passed a resolution that officially recognized the Florentine immigrant to the United States, Antonio Meucci, as the inventor of the telephone.
