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 the transmission of telegraphic signals at the University of Göttingen, in Lower Saxony, helping to create the fundamental basis for the technology that was later used in similar telecommunication devices. Gauss's and Weber's invention is purported to be the world's first electromagnetic telegraph. In 1840, American Charles Grafton Page passed an electric current through a coil of wire placed between the poles of a horseshoe magnet. He observed that connecting and disconnecting the current caused a ringing sound in the magnet. He called this effect "galvanic music". Innocenzo Manzetti considered the idea of a telephone as early as 1844, and
