On April 27, 1877, Alexander Graham Bell lectured at the Skiff Opera House in New Haven. Bell demonstrated a three-way telephone connection with Hartford and Middletown, inspiring George W. Coy to seek the Bell telephone franchises for those counties. By January of 1878, Coy had built the first commercial telephone exchange in the world, another Connecticut first.
