Before the development of the electric telephone, the term "telephone" was applied to other inventions, and not all early researchers of the electrical device called it "telephone". A communication device for sailing vessels The Telephone was the invention of a captain John Taylor in 1844. This instrument used four air horns to communicate with vessels in foggy weather.[2] Later, c. 1860, Johann Philipp Reis used the term in reference to his Reis telephone, his device appears to be the first such device based on conversion of sound into electrical impulses, the term telephone was adopted into the vocabulary of many languages. It is derived from the Greek: τῆλε, tēle, "far" and φωνή, phōnē, "voice", together meaning "distant voice".
Credit for the invention of the electric telephone is frequently disputed. As with other influential inventions such as radio, television, thelight bulb, and the computer, several inventors pioneered experimental work on voice transmission over a wire and improved on each other's ideas. New controversies over the issue still arise from time to time. Charles Bourseul, Antonio Meucci, Johann Philipp Reis,Alexander Graham Bell, and Elisha Gray, amongst others, have all been credited with the invention of the telephone.[3]
Alexander Graham Bell was the first to be awarded a patent for the electric telephone by the United States Patent and Trademark Office(USPTO) in March 1876.[4] The Bell patents were forensically victorious and commercially decisive. That first patent by Bell was themaster patent of the telephone, from which other patents for electric telephone devices and features flowed.[5]
In 1876, shortly after the telephone was invented, Hungarian engineer Tivadar Puskás invented the telephone switch, which allowed for the formation of telephone exchanges, and eventually networks.[6]
