‎First German edition (which originally appeared the same year in Danish in ""Oversigt over det Kongelige Danske Viidenskabernes Selskabs Forhandlinger"") of Lorenz' 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. AND: First appearance of RIEMANN'S important paper (issued posthumously) in which he introduces the concept of ""RETARDED POTENTIALS"". Riemann suggests that Poisson's equation be modified by introducing terms which, though too small to be appreciable in ordinary experiments, would be capable of accounting for the propagation of electrical effects through space with a finite velocity c. This, so far as it goes, is in agreement with the view now accepted as correct.""The procedure which Lorenz followed was that of which Riemann had suggested in 1858 (the present paper by Riemann, which was published for the first time in 1867), 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).""Maxwell seems to have considered the great paper of L. Lorenz on retarded potentials (published simultaneously in 1867 with a paper written in 1858 by B. Riemann on the same theme) as insufficiently supportive of his vision of a dynamical theory of theelectromagnetic field, whereas the present attitude is that Riemann and Lorenz made important contributions to the Maxwellian view."" (Kirk T. McDonald in ""Maxwell's Objection to Lorenz' Retarded Potentials"").‎

‎First edition of Laue's importent paper in which he gives an experimental proof of the non-addition and non-subtraction phenomena in respect of the velocity of light. - Laue was awarded the Nobel Prize in 1914.""Einstein’s special theory of relativity dispensed with the addition or subtraction of the velocities, hitherto assumed to be self-evident, and applied instead a special ""addition theorem."" In 1907 Laue demonstrated that this theorem readily yields Fizeau’s formula with the previously enigmatic Fresnel drag coefficient: u = c/n ± v(1 - 1/n2). Laue thereby furnished Einstein’s theory with an important experimental proof, which, along with the Michelson-Morley experiment and arguments from group theory, contributed to early acceptance of the theory. Having thus proved himself an expert in relativity theory, in 1910 Laue wrote the first monograph on the subject. He expanded it in 1919 with a second volume on the general theory of relativity"" the work went through several editions.""(DSB).‎
