5 euro Copper BU dedicated to the 150th anniversary of the invention of the telephone by Antonio Meucci.
Antonio Meucci is considered to all intents and purposes the inventor of the telephone. In 1871 he patented a device, called a telettrofono, which made it possible to communicate at a distance. As early as 1854 Meucci had built the first telephone prototype. Due to the precarious economic conditions, Meucci was unable to patent the telephone first.
He then tried to propose the invention to a New York telegraph company. On 7 March 1876 Alexander Graham Bell, who had probably seen Meucci's design, filed the patent, thus attributing the authorship of the telephone.
Only on 11 June 2002 did the United States Congress recognize Meucci's contribution to the invention of the telephone.
