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.
