Claude Chappe (December 25, 1763 – January 23, 1805) was a French inventor who in 1792 demonstrated a practical semaphore system that eventually spanned all of France. This was the first practical telecommunications system, and Claude was the first telecom mogul.

 The Chappe brothers determined by experiment that the angles of a rod were easier to see than the presence or absence of panels. Their final design had two arms connected by a cross-arm. Each arm had seven positions, and the cross-arm had four more permitting a 196-combination code. The arms were from three to thirty feet long, black, and counterweighted, moved by only two handles. Lamps mounted on the arms proved unsatisfactory for night use. The relay towers were placed from 10 to 20 miles (12 to 25 km) apart. Each tower had a telescope pointing both up and down the relay line. Image File history File links Chapperégulateur. ...
 In 1792, the first messages were successfully sent between Paris and Lille. In 1794 the semaphore line informed Parisians of the capture of Condé-sur-l'Escaut from the Austrians less than an hour after it occurred. Other lines were built, including a line from Paris to Toulon. The system was widely copied by other European states, and was used by Napoleon to coordinate his empire and army.
