Alexander Graham Bell ( ; born Alexander Bell; March 3, 1847 – August 2, 1922) was a Scottish-born Canadian-American inventor, scientist, and engineer who is credited with patenting the first practical telephone.

Bell considered his invention…

The telephone played a major communications role in American history from the 1876 publication of its first patent by Alexander Graham Bell onward.

Ordinary people either subscribed to telephone service themselves, or used a telephone in the neighborhood, including public pay telephones. Long-distance service was metered and much more…
