The first transmission of intelligible speech over electrical wires took place on 10 March 1876. Inventor Alexander Graham Bell called out to his assistant Thomas Watson, “Mr. Watson, come here! I want to see you.” This transmission took place in their attic laboratory located in a near here at 5 Exeter Place. A pioneer in the field of telecommunications, Alexander Graham Bell was born in 1847 in Edinburgh, Scotland.

On 10 August 1876, Alexander Graham Bell demonstrated on this site that the human voice could be transmitted electrically over distance. While family members spoke into a transmitter in Brantford, 13 km away, Bell was able to hear them at a receiver located in Paris. This test convinced Bell that his invention could be used for communication between towns and could compete successfully with the telegraph.
