Alexander Graham Bell is credited with being the inventor of the telephone since his patent and demonstrations for an apparatus designed for “transmitting vocal or other sounds telegraphically… causing electrical undulations” were successful. First Bell Telephone, June 1875.
Attributing the true inventor or inventors to a specific invention can be tricky business. Often credit goes to the inventor of the most practical or best working invention rather than to the original inventor(s).
Antonio Meucci, an Italian immigrant, began developing the design of a talking telegraph or telephone in 1849. In 1871, he filed a caveat (an announcement of an invention) for his design of a talking telegraph. Due to hardships, Meucci could not renew his caveat. His role in the invention of the telephone was overlooked until the United States House of Representatives passed a Resolution on June 11, 2002, honoring Meucci’s contributions and work.
