Samuel Morse
In addition to the telegraph, Morse invented a marble-cutting machine that could carve three-dimensional sculptures in marble or stone. He could not patent it, however, because of an existing 1820 Thomas Blanchard design.
Siemens family
Werner Siemens, a former artillery and engineering officer in the Prussian army, invented a telegraph that used a needle to point to the right letter, instead of using Morse code. Based on this invention, he founded the company "Telegraphen-Bauanstalt von Siemens & Halske" on 1 October 1847, with the company taking occupation of its workshop on 12 October. His business partner Johann Georg Halske, a master mechanic, was particularly involved in the construction and design of electrical equipment such as the press which enabled wires to be insulated with a seamless coat of gutta-percha, the pointer telegraph, the morse telegraph and measuring instruments. The company was internationalised soon after its founding. One brother of Werner represented him in England (Sir William Siemens) and another in St.Petersburg, Russia (Carl von Siemens), each earning recognition. In 1867 Mr Halske withdrew from the company because his more conservative views on company policy diverged from those of the rather venturous Siemens brothers.
