sir francis ronalds and the Electric Telegraph
International Journal for The History of Engineering & Technology, 2016Co-Authors: Beverley RonaldsAbstract:Two hundred years ago, Francis Ronalds brought vision, theoretical understanding and practical ingenuity to the first large-scale demonstration of the Electric Telegraph, but the technology was rejected by Government in 1816 as being ‘wholly unnecessary’. He halted his work in Electrical science and engineering at that time. The Telegraph was commercialised by others 20 years later (using several elements of his system) and he followed progress closely. His renown gradually grew as the network spread around the globe and, at the end of his long life, he formally joined the new Telegraph engineering profession and made a further offering to it in the form of the Ronalds Library. He was regarded by his colleagues as the first Electrical engineer and this view can also be argued today. Ronalds’ story is an example of the consequences of unthinking criticism in delaying deployment of new ideas and technologies.

the nervous system of britain space time and the Electric Telegraph in the victorian age
The British Journal for the History of Science, 2000Co-Authors: Iwan Rhys MorusAbstract:From its inception, Victorian commentators on the Telegraph appeared fascinated by its apparent capacity to break down barriers of space and time. They waxed lyrical over the ways in which the Telegraph would bring nations closer together, break down boundaries and foster commerce. They also eulogized the ways in which the Telegraph could be used as a seemingly effortless instrument of discipline. A great deal of work was needed to uphold such fantasies and make the Telegraph work. This paper highlights efforts to establish a Telegraphic time signal from Greenwich as an example of the labour and management required to sustain such rhetoric. Finally, the paper focuses on the increasingly common metaphor linking the Telegraph network and the nervous system. It suggests that the metaphor worked for the Victorians because both systems were held to operate through the instantaneous transmission of intelligence as a means of maintaining bodily and social discipline.

salva s Electric Telegraph based on volta s battery
2008 IEEE History of Telecommunications Conference, 2008Co-Authors: Perez A YusteAbstract:Contemporary of such important figures as d'Alembert, Buffon, Franklin, Kant, Betancourt or Goya, Francisco Salva y Campillo was also a prominent Enlightenment scientist who shared with all of them his passion for knowledge and his support to the empiricism and to the scientific method. Five years before Samuel Thomas von Sommering demonstrated his electro-chemical Telegraph to the Munich Academy of Sciences, Salva proposed a very innovative Electric Telegraph based on Volta's pile, for generating an Electric current, and the electrolysis of the water, for detecting such a current flow. Salva presented his Electric Telegraph to the Academy of Sciences at Barcelona, Spain, in 22 February 1804, and left his thoughts written in a not very well known essay titled: 'Second Report about Galvanism as applied to Telegraphy' which will serve as the basis for this paper.

a thorn in the side of european geodesy measuring paris greenwich longitude by Electric Telegraph
The British Journal for the History of Science, 2014Co-Authors: Michael KershawAbstract:The difference in longitude between the observatories of Paris and Greenwich was long of fundamental importance to geodesy, navigation and timekeeping. Measured many times and by many different means since the seventeenth century, the preferred method of the later nineteenth and early twentieth centuries made use of the Electric Telegraph. I describe here for the first time the four Paris-Greenwich Telegraphic longitude determinations made between 1854 and 1902. Despite contemporary faith in the new technique, the first was soon found to be inaccurate; the second was a failure, ending in Anglo-French dispute over whose result was to be trusted; the third failed in exactly the same way; and when eventually the fourth was presented as a success, the evidence for that success was far from clear-cut. I use this as a case study in precision measurement, showing how mutual grounding between different measurement techniques, in the search for agreement between them, was an important force for change and improvement. I also show that better precision had more to do with the gradually improving methods of astronomical, time determination than with the singular innovation of the Telegraph, thus emphasizing the importance of what have been described as 'observatory techniques' to nineteenth-century practices of precision measurement.
