The Chappe telegraph was extensively used in France by the government, so this arrangement was appealing to them as it meant there was no need to retrain operators. Most needle telegraph systems moved the needles by means of an electromagnet driven by battery power applied to the line at the sending end. In contrast, the Foy-Breguet telegraph ...
