Invention of the telephone trials involving Meucci and Alexander Graham Bell. They claim that Meucci was the actual inventor of the telephone, and base their argument on reconstructed evidence. What follows, if not otherwise stated, is a résumé of their historic reconstruction. The above information was published in the "Scientific American" Supplement No. 520 of December 19, 1876, based on reconstructions produced in 1885, for which there was no contemporary pre-1875 evidence. Meucci's 1871 caveat did not mention any of the telephone features later credited to him by his lawyer, and which were published in that Scientific American Supplement, a major reason for the
Invention of the telephone Company, and the results were covered up by STC's chairman Sir Frank Gill to maintain Bell's reputation. An early voice communicating device was invented around 1854 by Antonio Meucci, who called it a "telettrofono". In 1871 Meucci filed a caveat at the US Patent Office. His caveat describes his invention, but does not mention a diaphragm, electromagnet, conversion of sound into electrical waves, conversion of electrical waves into sound, or other essential features of an electromagnetic telephone. The first American demonstration of Meucci's invention took place in Staten Island, New York in 1854. In 1861, a description of it was
