1837 __ Telegraph with sound signals
Sibrandus Stratingh (1801-1870)
Comment : In 1837, Professor Stratingh, of Groninque, Holland, devised a telegraph in which the signals were made by electro-magnets actuating the hammers of two gongs or bells of different tone; and M. Amyot invented an automatic sending key in the nature of a musical box. (John Munro)
French comment : Mr. Stratingh a publié, dans un journal anglais, la description d'un télégraphe électro-magnétique à cloches : "Iets over eenen Elektromagnetischen Kilokke-Telegraaf", door S. Stratingh, Ez ; Tijdschrift ter bevordering van Nijverheid. (In "Archives de l'électricité", par Mr. A. de la Rive, Volume 3, 1843, Genève : B. Glaser, Paris : Anselin, p. 471)
