‎Scarce first edition of Lorenz' landmark paper, which contains his important studies on the electromagnetic theory of light in which he - less than two years after, but independently of, Maxwell - found that LIGHT MIGHT BE INTERPRETED AS ELECTROMAGNETIC WAVES, and that his equations lead to the CORRECT VALUE FOR THE VELOCITY OF LIGHT. ""The procedure which Lorenz followed was that of which Riemann had suggested in 1858, namely, to modify the accepted formula of electrodynamics by introducing terms which, though too small to be appreciable in ordinary laboratory experiments, would be capable of accounting for the propagation of electrical effects through space with a finite velocity...The (Lorenz-) equations are, however, the fundamental equations of Maxwell's theory"" and therefore the theory of L. Lorenz is practically equivalent to that of Maxwell, so far as concerns the propagation of electromagnetic disturbances through free aether.....he suggested that ALL LUMINOUS VIBRATIONS MIGHT BE CONSTITUTED BY ELECTRIC CURRENTS, and hence that there was 'no longer any reason for maintaining the hypothesis of an aether, since we can admit that space contains sufficient ponderable matter to enable the disturbance to be propagated"" (Edmund Whittaker in ""A History of the Theories of Aether and Electricity I"", p. 267-70).‎

‎Extremely scarce first edition of the paper in which Lorenz, independent of Maxwell, stated that light is electromechanical in nature, probably inspired by his former teacher H. C. Oersted, the discoverer of electromagnetism and professor at the Polytechnic College, he aimed at unifying the forces of nature without introducing new physical hypotheses. ""The idea that the various forces in nature are merely different manifestations of the one and same force has proved itself more fertile than all physical theories"".Most impressive of all Lorenz’ achievements in optics is his electromagnetic theory of light, developed in a relatively unknown paper of 1867, two years after Maxwell’s famous paper on the same subject. At that time Lorenz did not know Maxwell’s theory, and his own approach was quite different. Lorenz’ electromagnetic theory of light can be described briefly as an interpretation of the light vector as the current density vector in a medium obeying Ohm’s law. This paper contains the fundamental equations for the vector potential and the scalar potential or - for the first time - the corresponding retarded potentials expressed in terms of the current density vector and the electrical charge density. The concept of retarded potentials had already been introduced in an earlier paper by Lorenz in connection with research on the theory of elasticity. He found that the differential equation for the current density vector was the same as his fundamental wave equation for the light vector, completed with a term which explains the absorption of light in conducting media, and that his theory led to the correct value for the velocity of light."" (Mogens Pihl in DSB).The paper was published in English, 1867 ""On the identity of the vibrations of light with electrical currents."" (Philosophical Magazine 34: 287-301) and also in German in ""Annalen der Physik""‎

‎First apperance of Majorana's paper which was the first experimentally to prove the speed of light as set forth by Einstein in his special relativity theory. Majorana was critical to Einstein's relativity, and he therefore tried to prove experimentally that the postulate of the speed of light was wrong. His experiments turned out otherwise, and he hereby proved Einstein's postulate that the speed of light was independent of the velocxity of its source.‎

‎(London, Taylor & Francis, 1869) Large 4to. Without wrappers. Extracted from ""Philosophical Transactions of the Royal Society of London."", Vol. 158. Maxwell's paper: pp. 643-657. Clean and fine, wide margins.‎

‎First appearance of this major paper on electromagnetic dynamics, in which Maxwell improves the groundbreaking equations he had set forth in his famous paper of 1865, the ""A dynamical Theory of Electro-Magnetic Fields"". In the paper offered here, he for the first time proposed to base the electromagnetic theory of light solely on 2 equations. The paper is one of Maxwell's 5 most importent contributions to electromagnetism.""Formulas for the forces between moving charged bodies may indeed de derived from Maxwell's equations, but the action is not along the line joining them and can be reconciled with a dynamical principle only by taking into account the exchange of momentum with the field. Maxwell remarked that the equations might be condensed, but ""to eliminate a quantity which expresses a useful idea would be rather a loss than a gain in this stage of our enquiry."" he had in fact simplified the equations in his fifth major paper, the short, but importent ""Note on the Electromagnetic Theory of Light."" (1868), writing them in an integral form without the function A, based on four postulates derived from electrical experiments. This may be called the electrical formulation of the theory, in contrast with the original dynamical formulation."" (C.W.F. Everitt in DSB).‎

‎Announcing his discovery of ultraviolet light ""Von den Herren Ritter und Bückmann. - - Am 22sten Febr. habe ich auch auf der Seite des Violetts im Farbespectrum, ausserhalb desselben, Sonnenstrahlen angetroffen....‎

‎Halle, Rengerschen Buchhandlung, 1801. Without wrappers as published in ""Annalen der Physik. Herausgegeben von Ludwig Wilhelm Gilbert"", Bd. 7, Viertes Stück. The entire issue offered (=Heft 4). Pp. 387-528. Ritter's announcement p. 525. With titlepage to volume 7. Clean and fine. Titlepage a bit shavedin inner margin.‎

‎First printing of Ritter's announcement of his discovery of ultraviolet light in a halfpage letter addressed to Gilbert's Annalen. With that discovery, it became clear that visible light represents no more than a fraction of a continous spectrum.A year earlier, in 1800, William Herschel discovered infrared light. This was the first time that a form of light beyond visible light had been detected. After hearing about Herschel's discovery of an invisible form of light beyond the red portion of the spectrum, Ritter decided to conduct experiments to determine if invisible light existed beyond the violet end of the spectrum as well. He had heard that blue light caused a greater reaction in silver chloride than red light did. Ritter decided to measure the rate at which silver chloride reacted to the different colors of light. He directed sunlight through a glass prism to create a spectrum. He then placed silver chloride in each color of the spectrum and found that it showed little change in the red part of the spectrum, but darkened toward the violet end of the spectrum. Johann Ritter then decided to place silver chloride in the area just beyond the violet end of the spectrum, in a region where no sunlight was visible. To his amazement, this region showed the most intense reaction of all. This showed for the first time that an invisible form of light existed beyond the violet end of the visible spectrum. This new type of light, which Ritter called Chemical Rays, later became known as ultraviolet light or ultraviolet radiation (the word ultra means beyond). - Parkinson, Breakthroughs: 1801 P.‎
