The earliest telegraphy, the system to which the title refers, was optical, via the use of semaphore. The telegraph of Claude Chappe, invented in the late 18th century, was the first true optical system and was extensively used in France, and European countries controlled by France, during the Napoleonic era. A later optical telegraph was the heliograph, which used reflected light from the sun (used, for example, by the US Army in the southwest during the Apache wars). Electronic telegraphy developed separately in Britain and the United States in the mid-19th century.
