On May 24, 1844, the first long-distance telegraph line in the United States was successfully opened, connecting Washington, D.C., and Baltimore, Maryland. This milestone event was marked by Samuel Morse sending the famous message, “What hath God wrought,” from the U.S. Capitol to the B&O Railroad’s Mount Clare station in Baltimore. The successful operation of this 40-mile telegraph line demonstrated the practicality and reliability of Morse’s telegraph system, paving the way for the rapid expansion of telegraph networks across the United States and around the world. This innovation revolutionized communication by enabling instantaneous transmission of information over long distances.
