Historical contribution
What Chappe contributed
Claude Chappe and his collaborators demonstrated visual telegraphy during the French Revolution and established the Paris-Lille line in 1794. The first official traffic included rapid reports of military events such as the recapture of Le Quesnoy. French institutional sources contrast the minutes or hours of telegraphic delivery with the days previously required by road.
Why it mattered
Moves coded messages faster than physical transport across staffed line-of-sight routes.
