1,200-year-old telephone, amazing invention of the …
An earlier version of the telephone had been registered by an Italian-American named Antonio Meucci. He called his device the and used it to talk to his bedridden wife while he was working in a different room. He filed a caveat (a kind of stopgap patent) in 1871, five years before Bell's telephone patent, but couldn't afford to renew it. When Bell's patent was registered in 1876, Meucci sued. He'd sent his original sketches and working models to the lab at Western Union where Bell worked. Meucci died in 1889, while his case against Bell was still under way. As a result, it was Bell, not Meucci, who got the credit for the invention. And he only managed that by a few hours; American inventor Elisha Gray was also developing a system to transmit the human voice and filed his patent on the same day. Gray's patent was the 29th to be recorded on February 14 1876; Bell's was number five.

Field telephones are telephones used for military communications
Both Antonio Meucci and Elisha Gray should be credited with successfully inventing telephones in the United States before Alexander Graham Bell “invented” it in 1876. Others who performed pioneering experimental work with electrical voice transmissions over wires included Thomas Edison, Innocenzo Manzetti, Charles Bourseul and Johann Philipp Reis. The telephone, as we know it today, is largely based on improvements made by Thomas Edison on the original design—which was not Bell’s but Meucci’s.
