On this day in 1838, Samuel Morse’s telegraph was demonstrated
for the first time at the Speedwell Iron Works in Morristown, New
Jersey. The telegraph, a device which used electric impulses to transmit
encoded messages over a wire, would eventually revolutionize
long-distance communication, reaching the height of its popularity
in the 1920s and 1930s.
Samuel Finley Breese Morse
(April 27, 1791 – April 2, 1872)
