* Added - The first use of semaphore signals for practical use was by Claude Chappe, in France, in 1792. Chappe is acknowledged as the inventor of the semaphore. He developed the system to convey messages from city to city within France by a series of relay stations similar to the way a telegraph was used n later years. Prior to this development, messages could take more than a day to go from point-to-point that could be reached in less than 2 minutes under his system.
In 1793, Claude Chappe invented the first long-distance semaphore.
Semaphore was invented as a visual signaling system to relay messages over long distances. It was developed to communicate with ships at sea or between different points on land where other methods of communication like smoke signals or flags were not practical. Semaphore systems used different flag positions to represent different letters or words and were widely used before the invention of the telegraph.
The original use of semaphore was invented around 1792 by Claude Chappe. The use of semaphore flags was brought about during the 1800's on ships at sea.
It was invented in France. It was popular in the late 18thC

The semaphore flag signaling system was developed by Claude Chappe in France during the late 18th century. Chappe's system used a series of different flag positions to convey messages over long distances, and it was widely used for communication before the invention of the telegraph.
Semaphore was invented in 1648 by Robert Hooke. The first use was by Claude Chappe in 1792 in France. The system conveyed messages from city to city by relay stations or towers.
Semaphore communication was first used in the late 18th century by Claude Chappe in France, around the 1790s. Chappe developed a system of visual signals using large mechanical arms to communicate messages over long distances.
