Invention of the telephone Gray's led to the myth that Bell had arrived at the Patent Office earlier. Bell was in Boston on February 14 and did not know this happened until later. Gray later abandoned his caveat and did not contest Bell's priority. That opened the door to Bell being granted US patent 174465 for the telephone on March 7, 1876. In 1906 the citizens of the City of Brantford, Ontario, Canada and its surrounding area formed the Bell Memorial Association to commemorate the invention of the telephone by Alexander Graham Bell in July 1874 at his parent's home, Melville House, near Brantford.
History of the telephone worked mainly on a store and forward basis. Although telephones devices were in use before the invention of the telephone exchange, their success and economical operation would have been impossible with the schema and structure of the contemporary telegraph systems. Prior to the invention of the telephone switchboard, pairs of telephones were connected directly with each other, which was primarily useful for connecting a home to the owner's business. A telephone exchange provides telephone service for a small area. Either manually by operators, or automatically by machine switching equipment, it interconnects individual subscriber lines for calls made between them. This
