The invention of the telephone

It was at this time, 1876–1877, that a new invention called the telephone emerged. It is not easy to determine who the inventor was. Both Alexander Graham Bell and Elisha Gray submitted independent patent applications concerning telephones to the patent office in Washington on February 14, 1876. Bell, in Boston at the time, was represented by his lawyers and had no idea that the application had been submitted. Gray’s application arrived at the patent office a few hours before Bell’s, but Bell’s lawyers insisted on paying the application fee immediately; as a result, the heavily burdened office registered Bell’s application first.

Bell’s patent was approved and officially registered on March 7, and three days later the famous call is said to have been made when Bell’s summons to his assistant (“Mr Watson, come here. I want to see you.”) confirmed that the invention worked.
