Bell Memorial invention of the telephone in Brantford and to name Bell as its inventor. What was highly unusual in this instance was the building of an important monument to a living person, an event usually conducted only for imperial leaders. The duality of the monument with its dedication to both the inventor and to his invention, with its emphasis on the latter, likely persuaded Alexander Graham Bell, normally modest, to accept the invitation to its public unveiling. The association was organized with the support of George, Prince of Wales (later King George V), Viceroy of India and former Governor-General of Canada
Elisha Gray and Alexander Bell telephone controversy hooked up into the circuit. These experiments, with a vibrating wire touching a liquid, anticipated the liquid transmitter of Bell's telephone in March, 1876 three years later. (Compare Fig. 3 and Fig. 7, for example.) Initially, Bell was trying to develop a telegraph capable of sending multiple messages simultaneously over the same wire. Most of these early experiments involved "liquid transmitters" based on the Helmholtz model. On November 9, 1874, Bell's friend and neighbor, P.D. Richards, wrote the inventor a letter at Bell's request describing the experiments and transmission of telegraphic messages over wires using a liquid transmitter filled with
