Morse Opens the Electric Telegraph (24 May 1844) was a landmark science, technology & invention development in United States.
On 24 May 1844 Samuel F. B. Morse transmitted the message "What hath God wrought" from the Capitol in Washington to his partner Alfred Vail at a railroad station in Baltimore, the first public demonstration of his electromagnetic telegraph over the forty-mile line funded by a $30,000 congressional grant. Using the dot-and-dash code developed with Vail, the system allowed messages to travel at near the speed of electricity, collapsing the time required to move information across long distances from days to seconds. The electric telegraph rapidly spread along railway and trade routes, reshaping commerce, journalism, diplomacy, finance, and military command. Markets could be linked across continents, news agencies could report distant events almost in real time, and governments could coordinate over vast territories. Within a generation, networks of wires spanned North America, Europe, and colonial empires, and submarine cables began to connect continents. The telegraph is widely regarded as the first technology to separate communication from physical transport, inaugurating the modern era of instantaneous long-distance information exchange.
