EARLY TELEPHONES


Although Alexander Graham Bell is credited with inventing the telephone there were many others who were in the same position. Bell just pipped them all by getting a patent issued for transmitting sound.  His first telephone could only transmit sound and this is known as the Gallows telephone (1875).

Bell then continued to develop `his' ideas into a workable telephone and this took around two years as his original transmitter was not powerful enough.  Around 1877 he made the first commercial telephone that resembled a small box camera.
