Claude Chappe presented the Semaphore, a groundbreaking visual telegraph system that revolutionized long-distance communication in the late 18th century. This innovative system used a series of pivoting wooden arms mounted on towers, which could be positioned to represent different letters and numbers. By placing these towers at intervals across the countryside, messages could be rapidly relayed from one station to the next, significantly reducing the time it took to transmit information over long distances. Chappe’s Semaphore was a precursor to modern telecommunication and played a crucial role in military and governmental communication during its time.
