Antonio Meucci was the first person who demonstrated a working model of an electric device called the “teletrofono”. He made it 5 years before Alexander Graham bell’s telephone patent.
Since Meucci got Ill, he failed to send the $10 required to renew his caveat in 1974.
When Graham bell patent was registered in 1876, Meucci sued. He’d sent his original sketches and working models to the lab at Western Union. By an extraordinary coincidence, Bell worked in the very same lab and the models had mysteriously disappeared.
Meucci died while his case against bell was still under way. As a result, it was Bell, not Meucci who got the credit for the invention.
In 2004, the balance was partly redressed by the US House of Representatives who passed a resolution that “the life achievement of Antonio Meucci should be recognized, and his work in the invention of the telephone should be acknowledged”.
