København, Andr. Fred. Høst & Søn, 1920. Three volumes in three. Large 4to (28.9 x 20.1 cm). clxvi, 1358 pp., three frontispiece portraits, numerous text figures. Original uniform printed wrappers. = A very uncommon if not rare collection of Ørsted's work with two additional essays on his work by Kirstine Meyer. Written in German and Danish, Latin and French, depending upon where Ørsted published his work. The essays by Meyer in English. The Danish physicist and chemist Hans Christian Ørsted, or Oersted (1777-1851) is principally known for his reseaches in electromagnetism. He "discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. He is still known today for Oersted's Law. He shaped post-Kantian philosophy and advances in science throughout the late 19th century. In 1824, Ørsted founded Selskabet for Naturlærens Udbredelse (SNU), a society to disseminate knowledge of the natural sciences. He was also the founder of predecessor organizations which eventually became the Danish Meteorological Institute and the Danish Patent and Trademark Office. Ørsted was the first modern thinker to explicitly describe and name the thought experiment. A leader of the so-called Danish Golden Age, Ørsted was a close friend of Hans Christian Andersen . The oersted (Oe), the cgs unit of magnetic H-field strength, is named after him" (Wikipedia). Small, weak stamp on Danish title pages and front covers; library labels on spine feet; top of spine of volume I with short tear and chip, otherwise a very good, clean set.…

Kjøbenhavn (Copenhagen), Andr. Fred. Høst, 1850. 8vo. Bound in a beatiful later half-morocco binding with richly gilt spine. (Anker Kysters Eftf. 1971). Spine slightly faded. Scattered brownspots, otherwise internally clean. Printed on vellum paper. X,190"XII,206 pp. First edition of Oersted's main work on natural philosophy. Oersted is universally known for his discovery of Electro-Magnetism in 1820. Afterwards he went on to write a number of important philosophical works on natural philosophy and empiricism, of which he considered "Aanden i Naturen" as his main work. The work is found printed on 2 sorts of paper, common- and vellum paper, the present copy being on vellum. Both Hans Christian Andersen and Søren Kierkegaard admit to having been influenced by the writings of Oersted. "He was an enthusiastic follower of the "Naturphilosophie" school in Germany, whose main object was the unification of physical forces, thus producing a monistic theory of the universe. It was to further this purpose that Oersted sought in actual phenomena the electro-magnetic identity of which he had already convinced himself on metaphysical grounds" (Percy H. Muir in Printing and The Mind of Man). The copy once belonged to the renowned Danish book collector Gustav Philipsen (1853-1925) and carries his exlibris.…

Oersted & Fourier's paper: pp. 375-389 and 1 folded engraved plate. showing apparatus used. First appearance of this importent paper - which can bee seen as the precursor of OHM'S LAW - in which Ørsted explains the experiments he did together with Fourier on the thermo-electric effects discovered by Seebeck. They proved with different experiments, that the effect depended solely on the heating of the plates in the voltaic arrangements. Ørsted calls Seebech's observations "the most beautiful of the discoveries which have as yet grown out of mine (his discovery of electromagnetism three years before)"We learn from his letters that thet the experiments on which the paper was founded had taken him 3 weeks, a space of time which evidently much too short for the performance of the work" thus Ørsted himself points out a fundamental flaw in the experiments, but there has been no time to remedy it. The work is of interest, both by what has been gained through it, and by what does not plainly appear" in some of its results it is the precursor of Ohm's law and by its defects it shows how great was the feat of the actual discovery of this law."(Kirstine Meyer).The offered issue contains further Poisson "Sur le Phénomene des anneaux colorés", pp. 337-347., Ørsted "Sur le Multiplacateur électro-magnetique de M.

(Paris, Crochard, 1823). 8vo. Without wrappers as extracted from: "Annales de Chimie et de Physique, Par MM. Gay-Lussac et Arago.", Vol. 22, pp. 375-389. First appearance of this paper, revealing the results of experiments with the galvanic elements, using pairs of small antimony and bismuth bars welded in series, which Oersted performed together with Fourier during his visit to Paris. This constitutes the invention of the first thermo-electrical pile. Oersted and Fourier had found that heat had a significant effect upon the performance of the galvanic element. - "Seebeck seems to have had another theory about this. However, I have experimented with the matter, and found the conjecture correct. I believe that this discovery will be of far-reaching consequence. The laws for this new effects are, I suppose, in reality the same as for the galvanic battery" yet this looks so different that I have been obliged to spend a great deal of my time during the last fortnight in discovering and defining them.". In a letter of somewhat later date to prince Christian, he states that he has made the experiments "in conjunction with Fourier, the secretary of the mathematical department of the Institute". Oersted, when reading this paper to the Academy on 31st of March 1823, proposed the name "thermo-electric" for these currents, a name which has since been adopted everywhere.

Kiøbenhavn, Andreas Seidelin, 1820. 8vo. In contemporary brown half calf with lighter brown leather title-label with gilt lettering. All edges coloured in blue. In: "Dansk Litteratur = Tidende for Aaret 1820". (The entire volume 1820 present, comprising all 52 issues, numbered 1-52). Light wear to extremities, spine with a few scratches. With occassional brownspotting, primarily affecting first and last leaves, but generally nice and clean. (Entire volume:) X, 822 pp. (Oersteds paper's in issue no. 28:) pp. 447-448. The exceedingly rare very first announcement of H. C. Ørsted?s landmark discovery of electromagnetism, predating his famous ?Experimenta?-paper by at least a week. Publishing the present brief note allowed him to quickly claim priority for his discovery, which ensured that his work would be recognized and attributed to him before others potentially stole his discovery. The importance of the discovery of electromagnetism, one of the most pivotal moments in the history of science, can hardly be overestimated. Here, Ørsted laid both the theoretical and practical foundation for future works of Faraday, Maxwell, and Hertz. The offered paper was published in the 28th week of July, 1820 (No. 28 of the periodical), which means that it was published some time between July 11 and July 16, probably the 11th or 12th. The paper which made Oersted famous all over Europe was his Latin pamphlet "Experimenta circa effectum conflictus electrici in acun magneticam. Hafniæ, 1820", dated July 21, 1820. The Latin ?Experimenta? was sent on the same day (according to Kirstine Meyer in "Scientific Life and Works of H.C. Ørsted") to learned bodies and scholars in all European countries. The communication offered here (in Danish) was published at least a week before "Experimenta". The essence of Oersted's discovery is detailed in the paper offered here, where he describes how the magnetic effect of an electric current-carrying wire was initially observed using an incandescent platinum wire. He then extended his experiments to non-incandescent wires made from various materials noting that the magnetic effect was influenced by the wire's dimensions. Among Oersted's papers (now in the holding of the Danish Royal Library), we have both a draft written in his own hand on acid-stained paper and a nearly identical version in another handwriting. These experimental notes form the basis of the present paper (which Kirstine Meyer refers to as "Supplement II"). In Supplements III and IV (dated July 15 and 21), Oersted further elaborates on his experiments with the wire in different positions relative to the magnet which became his ?Experimenta?-paper. ?Electromagnetism itself was discovered in the year 1820, by Professor Hans Christian Oersted, of the University of Copenhagen. Throughout his literary career, he adhered to the opinion, that the magnetical effects are produced by the same powers as the electrical. He was not so much led to this, by the reasons commonly alleged for this opinion, as by the philosophical principle, that all phenomena are produced by the same original power. ? His researches upon this subject, were still fruitless, until the year 1820. In the winter of 1819?20, he delivered a course of lectures upon electricity, galvanism, and magnetism, before an audience that had been previously acquainted with the principles of natural philosophy. In composing the lecture, in which he was to treat of the analogy between electricity and magnetism, he conjectured, that if it were possible to produce any magnetical effect by electricity, this could not be in the direction of the current, since this had been so often tried in vain, but that it must be produced by a lateral action. This was strictly connected with his other ideas" for he did not consider the transmission of electricity through a conductor as an uniform stream, but as a succession of interruptions and reestablishments of equilibrium, in such a manner that the electrical powers.…

Leipzig, Johann Ambrosius Barth, 1820. Contemporary half calf. Raised bands, gilt spine. Spine slightly rubbed. "Annalen der Physik. Hrsg. von Ludwig Wilhelm Gilbert", Bd. 66. Small stamps on verso of title-pages (2) and verso of plates. (12), 426 pp., 1 folded table a. 3 engraved plates. The entire volume offered. Oersted's paper: pp. 295-304. Internally clean and fine. First edition of the first German translation (by Gilbert) of Oersted's epoch-making announcement of his discovery of electromagnetism, printed in the same year as the Latin original. The work originally appeared in Latin as "Experimenta circa effectum conflictus electrici in acun magneticam. Hafniæ, 1820"" this Latin pamphlet is impossibly scarce and only a few copies are known, as it was privately printed in a very small number and was only distributed to colleagues in Europe. This discovery and confirmation of the connection between 2 forces, electricity and magnetism, must be considered one of the happiest events in the history of science, both with regard to scientific and practical results."From the moment that Ørsted's discovery became known it created an enormous sensation. The results communicated were so astounding that they were received with a certain distrust, but they were stated with such accuracy that it could hardly be permitted to entertain any doubts. In the course of a short time the treatise was translated into all the chief languages." (Kirstine Meyer). In a note Gilbert says, that it is a word by word translation of Oersted's small Latin pamphlet, "Eine fast wörtliche Uebersetzung des einzeln gedruckten, lateinischen, de 21 Juli 1820 geschriebenen Viertel-Bogens, de von Hrn. Oersted mehreren zugeschicht worden ist."When Oersted's discovery became known to European physicists they became busy with testing Oersted's results" thus, this volume of "Annalen" contains some important papers on electromagnetism in German: Gilbert: Untersuchungen über die Einwirkung des geschlossenen galvanisch-electrischen Kreises uaf die Magnetnadel. pp. 331-391" Biot & Savart: Von einer Abhandlung über die Magnetismus der Voltaischen Sáule (The Law of Biot & Savart), pp. 392-394 (German extract) Yelin: Ueber den Zusammenhang der Electricität mit dem Magnetismus.mit einigen Zusätzen von Gilbert.
