  • On March 7, 1876, Alexander Graham Bell received a patent for the telephone. The invention of the telephone revolutionized the way people communicate with one another. The device allowed people to instantly and effectively talk to each other over long distances.

    When Bell died in 1922, phones throughout the United States had a moment of silence, to honor the man who made those phones possible. The Bell Telephone Company eventually became AT&T, which is still in operation more than 125 years later.
