The telegraph was built using a system of electrical signals transmitted over wires. Samuel Morse and Alfred Vail developed the first practical telegraph in the 1830s, using a simple circuit and Morse Code to encode messages. The construction involved laying insulated copper wire along poles or underground, connecting it to a battery at one end and a receiver, typically a relay or sounder, at the other. This innovation significantly reduced communication time over long distances.
Samuel Morse was the father of the telegraph and of Morse code. He built his first line between Washington DC and Baltimore in 1843.
