“…The firm completed it in time for the election on March 28, 1849, of King Friedrich Wilhelm IV of Prussia as Germany's hereditary emperor. The transmission of this result to Berlin, 500 km away, within an hour, was a triumph for electric telegraphy and the young company [26]. The introduction of electrical telegraphy to the public sector that autumn, following the transfer of the telegraph service from the Ministry of War to the Ministry of Commerce, was also very welcome.…”

“…The scientific level of the Prussian Military Academy, intermediate between those of a trade school and an engineering college, provided Werner with advantages over many of his generation with only empirical practical training [12]. He conducted a number of experiments on gunpowder and detonation mechanisms, as well as on an improved governor for steam engines [13] and the recently discovered chemical method of electrotyping [14].…”

“…His interest in electrical experiments had been vividly stimulated by working with Ferdinand Leonhardt, a skillful watchmaker and mechanic who experimented on telegraphy [16]. They had worked together in the artillery workshop on using electricity to measure the velocity of projectiles at any stage of their flight [17].…”

“…He wrote to his brother Wilhelm shortly after his 30th birthday in 1846, reflecting on the plans he imagined for his future: " … I have now practically decided to make a career of telegraphy, whether in or out of the army. Telegraphy will become an important branch of scientific technology in its own right and I feel the call to further its organization since I am convinced that it is still in its early childhood … " [21].…”

“…Declining to take advantage of his position in the Telegraph Commission, Werner instead joined with Halske to found the firm of Telegraphen-Bauanstalt von Siemens & Halske, on October 1, 1847. The capital required for the business, which was small since the individual telegraphs were hand-crafted and there was no need to purchase large machinery, came from Siemens' cousin, magistrate Johann Georg Siemens [24]. The investment of 6842 Prussian thalers (equivalent to about $130 000 in 2015), made the investor a partner with a fifth share in the profits.…”

T he technology of electric telegraphy that revolutionized longdistance communication and established the groundwork for later innovations, such as telephone, fax machine, and internet, emerged in the 1830s and 1840s thanks to the work of many men of science and technology around the world. In 1799, Alessandro Volta's invention of reliable storage electric currents which allowed their use in controlled conditions, and the demonstration two decades later of a connection between electricity and magnetism by Hans Christian Oersted, supported the experimentation which led to a communication system by which electric signals were transmitted over a wire laid between stations.The invention of the electrical telegraph has been popularly credited to two sets of researchers, William Fothergill Cooke and Charles Wheatstone in England, and Samuel Finley Breese Morse, Leonard Dunnell Gale, and Alfred Lewis Vail in the United States. There were others, however, who contributed both to the technical development of the idea as well as to its diffusion around the world. One was the visionary inventor, industrialist, and founder of Europe's oldest existing electrotechnical enterprise, the German Ernst Werner Siemens ("von" since 1888). This article focuses on Werner's achievements in the field of telegraphy and the way he contributed to its consolidation as a communication system, even in isolated parts of the world.

In 1892 the celebrated physicistand chemist William Crookes commented on the existence of “an almost infinite range of ethereal vibrations or electrical rays,” which he believed could revolutionize telegraphic communications (174). A few years later, and aided by Crookes's experiments with vacuums, the German physicist Wilhelm Röntgen successfully produced X-rays, a hitherto unrecorded form of electromagnetic radiation, which he tantalizingly described as “a new kind of invisible light” (Röntgen 413; Warner 256). Crookes was quick to speculate as to “the possibility of links between roentgen rays and the cerebral ganglia,” that an undiscovered organ in the brain might be “capable of transmitting and receiving . . . electrical rays” (Lyons 105; Crookes 176). X-rays, he thought, might prove a psychic counterpart to higher wavelength radio waves, allowing the transmission of messages telepathically rather than telegraphically, and even communication with the world of the spirits (Lyons 105). Crookes theorized that the parapsychological was intimately entwined with the findings of contemporary physics, occupying different zones of the same electromagnetic spectrum. An ardent Spiritualist, he believed that the ether, the “impalpable, invisible entity, by which all space is supposed to be filled” and which contained countless “channels of communication” also sustained “ghost-light . . . invisible to the naked eye” and acted as a medium that allowed “ethereal bodies to rise up” (Crookes 174; Warner 253–56). In other words, the matter through which light and electrical signals passed was envisaged as the same substance which allowed the spirits to fluctuate between visible and invisible forms. These links between the electromagnetic field and the occult, endorsed by Crookes and certain other members of his circles such as the Society for Psychical Research, anticipated turn-of-the-century associations between electricity, radiation and ancient Egypt which, through its reputation as the birthplace of magic, was central to Victorian conceptions of the supernatural.
