It is a far cry from Bell’s first telephone to Universal Service.

Bell’s invention had demonstrated the practicability of speech transmission, but there were many obstacles to overcome and many problems to be solved before the telephone could be of commercial value and take its place among the great public utilities.

Professor Bell had demonstrated that two people could talk to each other from connected telephones for a considerable distance. In order to be of commercial value, it was necessary to establish an intercommunicating system in which each telephone could be connected with every other telephone in the system. This has been accomplished through the invention of the multiple switchboard and a great number of inventions and improvements in all the apparatus used in the transmission of speech.

But it was an unexplored field into which the telephone pioneers so courageously plunged. There were no beaten paths, and the way was beset with unknown perils; there was no experience to guide. A vast amount of educational work had to be done before a skeptical public would accept the telephone at its true value, yet courage and persistency triumphed. Discoveries and inventions followed scarcely less important than Professor Bell’s original discovery.
