About this Item

SIEMENS, Werner. "On the Conversion of Dynamical into Electrical Force without the Aid of Permanent Magnetism" pp 367-369. AND with Charles Wheatstone, "On the Augmentation of the Power of a Magnet by Reaction thereon of Currents induced by the Magnet Itself", pp 369-372. AND James Clerk Maxwell, "On the Theory of the Maintenance of Electric Currents by Mechanical Work without the Use of Permanent Magnets" pp 397-402.[++] All in Proceedings of the Royal Society of London, volume 15, 1867, Taylor and Francis, London. viii, 546, xlviipp, with 11 plates (lacking plate 6)/ Completely rebound in half calf and marbled boards--the boards have been antiqued. There are a number of institutional rubber stamps in the text--they appear on the title page, on the backs of the plates, and about 14 other places in the test. This is a bright, crisp copy. These are significant papers here presented by Werner Siemens, Charles Wheatstone, and James Clerk Maxwell. Siemens (building on the earlier work of others, notably H. Pixii, who created a rotating magnet and coil apparatus that produced an alternating current in 1832, and of course the epochal work of Faraday in 1830) contributes this important work at virtually the identical time and space with along with Wheatstone (of the "Wheatstone bridge", 1833), who had been working independently of Siemens, both of whom presented their work on a dynamo that used self-powered electromagnets rather than general/permanent magnets. This is the first appearance in English of this report, which was original red to the Prussian Academy of Science by Siemens' friend, Heinrich Gustav Magnus, on 17 January 1867. As mentioned there was a certain "something" in the air so to speak in the development of dynamo-electric power, with a number of experimenters working very closely in the same area at the same time, though it seems that Siemens was truly the one who appreciate what the future might hold for this new electrical development. [++] Clerk Maxwell also contributes a paper later in the year in this same volume on the subject describing his dynamo (pp397-402), which is followed in turn by two short notices on the various dynamos described earlier (appearing on pp 403-404). [++] ALSO in this volume is James Clerk Maxwell, "On the Dynamical Theory of Gases" pp167-171, which is presented as a five-page "abstract" for the great 40pp) paper that would appear in fuller form later in the year in the "Philosophical Transactions" (vol 157).
