first transmitted sound over wires.
This successful experiment was completed in a fifth floor garret at what was then 109 Court Street and marked the beginning of world-wide telephone service.

The experiment referred to on this marker occurred when Alexander Graham Bell and Thomas Watson were trying to perfect a “harmonic telegraph” — one that could use different sound-wave frequencies to transmit several telegraph signals (more than one message) simultaneously over the same wire. In his 2010 book, A City So Grand: The Rise of an American
Metropolis, Boston 1850–1900, Stephen Puleo describes how the men were in different rooms when Watson, trying to get a stuck reed to vibrate, gave it a pluck. Bell, in the receiving room, distinctly heard the “twang” of the reed and instantly realized that if this complex sound could be transmitted over a wire, so might a human voice.
Within a few months Bell rented new space on Exeter Street in Boston, several blocks south of here, so they could continue their experiments. It was in the Exeter Street lab that on March 10, 1876, Bell transmitted his famous
