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.
