Siemens pointer telegraph

In the mid-19th century, electricity made it possible to profoundly revolutionize communications. Recognizing the importance of this development, Werner von Siemens designed and built an electric pointer telegraph that worked reliably and was superior to earlier devices of the kind. This innovation was the basis for “Telegraphen-Bauanstalt von Siemens & Halske,” which he founded in Berlin on October 1, 1847, together with precision mechanic Johann Georg Halske.
