‎First edition of Hertz's seminal paper on electromagnetic waves in which he empirically demonstrates Maxwell's equations. This discovery and its demonstration led directly to the invention radio of communication, television and Radar.Hertz demonstrates what Maxwell had predicted that electromagnetic waves radiated in space with the speed of light. Hertz determined these waves to be of greater length than light and that they could be reflected.""Experimental proof by Hertz of the Faraday-Maxwell hypothesis that electrical waves can be projected through space was begun in 1887, eight years after Maxwell's death. The two main requirements were (a) a method of producing the waves, supposing that they existed, and (b) a method of detecting them once they were produced."" (PMM, 377.). In the present paper Hertz ""describes the apparatus that he had devised for the detection and measurement of electromagnetic waves, the key to his later success. To prove that electromagnetic waves can be projected through space it was necessary to devise a means of both producing the waves and, more difficult at the time, of detecting them once produced."" (Norman Library, No. 1123).""Hertz's researches on electrical waves vindicated the Helmholtz ideal of the physicist as one whose competences embraced both experiment and mathematics. Hertz entered physics at the right time for one of his abilities to make a critical contribution"" because the outstanding problem of physics was the disorderly condition of electrodynamics, what was needed was someone with the theoretical power to analyze the competing theories and with the experimental judgment to produce the evidence that would persuade the physical community that a decision between the theories had been reached."" (DSB, VI, 348b.)In ""Ueber einen Einfluss des ultravioletten Lichtes auf die electrische Entladung"" Hertz describes for the first time in history the phenomenon that the sparking distances between two electrodes is increased when ultra-violet light falls on the negative conductor. ""In the early 1890's the young inventor Guglielmo Marconi read of Hertz's electric wave experiments in an Italian electrical journal and began considering the Possibility of communication by wireless waves.

‎First printing of Röntgen's early paper on the heat absorption in vapor. ""Having constructed a very sensitive air thermometer, he was able to measure the absorption of heat in water vapor, and his flair for experiment was also shown by his work on the compressibility of liquids and solids.""(DSB XI, p.530).An. HERTZ'S paper: This is a major paper by Hertz in which he gives simple proofs of Maxwell's fundamental equations. ""In 1884, at Kiel, Hertz had already carried out a study of Maxwell's theory. It was a theoretical response to Helmholtz' general problem of deciding between the electrodynamical theories. Whereas Helmholtz had shown that the experimental decision lay with unclosed currents, Hertz showed that a theoretical decision could be made on the basis of predictions for closed currents. Hertz proved that Maxwell's equations were compatible with the physical assumptions shared by all electrodynamical theories and that the equations of the contending theories were not. He concluded that if the choice lay solely between Maxwell's equations and the equations of the other type of theory, then Maxwell's were clearly preferable.""

‎First edition of Hertz' seminal book on electromagnetic waves, which laid the foundation of radiotelegraphy and radiotelephony.While investigating Maxwell's conception of light as an electromagnetic phenomenon, Hertz exposed that waves of electricity could both be transmitted and received through space. This had profound consequences and led, amongst other things, to Marconi's perfection of wireless telegraphy. ""His [Hertz'] discovery of the properties of reflection, refraction, and polarization in electricity, with this wave theory of electrical motion, laid the foundation of radiotelegraphy and radiotelephony."" (Milestones of Science, p 47.)""Experimental proof by Hertz of the Faraday-Maxwell hypothesis that electrical waves can be projected through space was begun in 1887, eight years after Maxwell's death.

‎Egenhændigt brev med underskrift til Hagerup. - [FESTEN FOR FRU HEIBERG]‎

‎Dateret ""25de Nov. 1842."" 1 side 4to. Tæt beskrevet. Opklæbet på pap, m. mindre tab. Brevet omhandler en sang af Ploug i forbindelse med en fest for Fru Heiberg, og det indeholder et langt citat af et andet brev, som Hertz har sendt Ploug i denne anledning. Brevet begynder ""For at overbevise Dem om, at jeg har opfattet Deres/ Meddelelse af Hr. Plougs Sang ganske som De i Deres Ords ...(?)/ fremstiller det, kan jeg ikke gjøre bedre end at afskrive mit, Onsdag Efter-/ middag afsendte Svar paa det brev, jeg fandt ...(?) af Hr. Ploug."" Herpå følger afskriften, i hvilken Hertz undskylder og skriver, at han var ""uvidende om, at De ønskede den holdt anonymt"""" derudover kommer Hertz ind på spørgsmålet om, hvorvidt det var passende, at den pågældende sang af Ploug blev sunget til festen, ""men min Mening, om jeg fandt det/ tilraadeligt, at der blev afsungen meer end een Sang"" og/ det sidste bad jeg Vedkommende selv at afgjøre."" Hertz slutter brevet: ""Med Hilsen og Tak til Dem og Deres Medarrangører for den smukke Maade, hvorpaa Festen for Fru Heiberg blev holdt, er jeg Dem ærbødigst/ Henr. Hertz.""‎

‎First edition of this importent paper in which Hertz went beyond Maxwell and hereby took the first step on the way to RELATIVITY THEORY.In his second theoretical paper (the paper offered), Hertz applied Maxwell’s equations to moving, deformable bodies. Maxwell had not treated this problem systematically in the Treatise although, unknown to Hertz, he had done so elsewhere. Hertz recognized that to develop an electrodynamics of moving bodies, it was first necessary to specify whether or not the ether moves with bodies. For his part he would assume that the ether is mechanically dragged by moving bodies. The first ground for this assumption was that within the restricted domain of electromagnetic phenomena there was nothing incompatible with the idea of a dragged ether. The second ground was that its denial entailed the complication that two sets of electric and magnetic vectors had to be assigned to each point of space, one for the ether and one for the independently moving body. He recognized at the same time that a dragged ether was an unsure foundation for electrodynamics....""(DSB).Schilpp ""Einstein"" pp. 31 ff. - Whittaker ""A History of the Theories of Aether and Electricity"", pp. 328 ff.‎

‎First apperance of these two groundbreaking papers constituting the famous ""Franck-Hertz Experiments"" giving the first experimental determination of Planck's constant not using blackbody radiation.""Thus, the experiments by Franck and hertz were later considered as a new and independent support not only of Planck's quantum theory and Einstein's light-quantum hypothesis, but also of Bohr's theory of the atom with sationary states of discrete energies. In 1926 Franck and Hertz were awardedthe Nobel prize for 1925.""(Siegmund Brandt ""The Harvest of a century"", Episode 25, p. 102).The Nobel Prize were given ""for their discovery of the laws governing the impact of an electron upon an atom"".‎

‎Manuscrit préparatoire de Contribution à la figure de Max Jacob‎

‎ 1947 4 ff. anopistographes (27 x 20 cm, environ 36 lignes par page) densément raturés et corrigés, au verso d'un papier à en-tête du journal "Excelsior" + photocopie de la dernière page du texte (27 lignes). Circa 1947.‎

‎Première étape de l'article de Hertz sur Max Jacob, qui fut publié dans les Lettres françaises (n° 179, 1947), puis dans Europe (48:489, janv. 1970, pp. 137-41). La bibliothèque de l'Alliance Israëlite Universelle, où furent déposées une grande partie des archives Henri Hertz, dispose d'une étape plus avancée du manuscrit (également 4 ff. sur le même papier à en-tête, AP 5 / 15). Henri Hertz raconte dans cet article sa rencontre avec Max Jacob, chez Apollinaire, avec lequel il entretint des relations amicales, de même qu'avec Picasso. Sa contribution à la Phalange, ainsi que le mysticisme de ce juif converti au catholicisme sont également évoqués. Henri Hertz (1875, Nogent-sur-Seine, 1966, Paris) n'est pas pour rien dans le lancement de la carrière littéraire de Max Jacob, dont il fut très proche. En 1895, il s'installe à Paris et collabore à la Revue Générale Internationale de Louis Gastine. En 1901, il publie les Contes de la Soif dans la Revue des Indépendants puis entre à la Revue Blanche, dirigée par les frères Natanson. Quelques années plus tard, il se lie d'amitié avec Max Jacob et Apollinaire. En 1909, il publie la pièce Des Mécréants, Grasset, et en 1912, les Apartés, Éditions de la Phalange, recueil de vers bien salué par la critique.Max Jacob a dit de lui que "c'est l'un des écrivains les plus singuliers du moment", et "qu'il y a du dadaïsme, gidisme et tout le naturalisme au complet" dans son oeuvre. Apollinaire le cite dans sa conférence sur la Phalange Nouvelle en 1908. Il est un des collaborateurs de sa revue Le Festin d'Esope. Ami de Jean Royère, directeur de la Phalange, il donnera des textes à sa revue. Il collabore activement, avec Apollinaire, Jacob, Royère, Klingsor, Soupault, Reverdy, Fagus, Valéry, Aragon, Canoudo, Viélé-Griffin, Breton... à la Revue les Trois Roses, fondée à Grenoble, en juin 1918, par Justin-Frantz Simon. Henri Hertz reçoit le Prix Mallarmé pour l'ensemble de son oeuvre en 1928. Bel état. ‎

‎First printing of Hertz' doctoral dissertation on the electromagnetic induction in rotating conductors, a purely theoretical work that took him only three months to complete.""It was not a pioneering work but a thorough study of the problem that had been partially treated by many others, from Arago and Faraday to Emil Jochmann and Maxwell. He submitted the dissertation in January 1880 and took his doctoral examination the following month, earning a magna cum laude, a distinction rarely given at Berlin.""(DSB).‎

‎First apperance of the famous Franck-Hertz Experiment which is considered as a new and independent support, not only of Planck's quantum theory and Einstein's light-quantum hypothesis but also of Bohr's theory of the atom with stationary states of discrete energies.Franck and Hertz were awarded the Nobel Prize in Physics in 1925 for this work and Franck concluded his Nobel lecture with the words ""We know only to well that we owe the wide recognition that our work received to contact with the great concepts and ideas of M. Planck and in particular Niels Bohr.""""In their famous experiments, Franck and Hertz' showed that electrons could impart energy to a mercury atom only if they had a kinetic energy exceeding 4.9 ev., and that exactly this quantum of energy was taken up by the mercury atom, causing it to emit light of the resonance line Å 2537. It was the first direct proof of the quantized nature of the energy transfer and of the connection of the quantum DeltaE of energy with the frequency p = DeltaE/h of the light emitted as the result of the transfer. These experiments are rightly regarded as the first decisive proof of the reality of the quantized energy levels that had just been postulated by Niel’s Bohr..."" (DSB).See: Siegmund Brandt ""The Harevest of a Century. Discoveries of Modern Physics in 100 Episodes"", Episode 25, The Franck-Hartz Experiment (1914), pp. 102-104.The volume contains another importent paper ALBERT EINSTEIN ""Beiträge zur Quantentheorie"", pp. 820-828. First edition. ""In this paper.... two considerations are given which are interrelated by a common goal, inasmuch as it is attempted to derive two of the most importent achievementss of quantum theory, viz. Planck's radiation law and Nernst's third law of thermodynamics, in a new manner. The proofs do not involve Boltzmann's equation and are thus based enterely on macroscopic thermodynamics. They do introduce, however, the quantum hupothesis. (Einstein points out that the alleged 'proofs' which try to derive the theorem of Nernst from the mere fact that the heat capacity of all substances goes to zero at absolute zero temterature, are not genuine).""

‎First printing of Hertz's first paper by which he won the Philosophical Faculty Prize (Berlin) in 1879, earning a medal, a first publication in Annalen der Physik and Helmholtz' deepening respect.""To encourage experimental work in the notoriously difficult domain of unclosed currents, Helmholtz proposed for the prize of the Berlin Philosophical Faculty in 1878 a problem dealing with an implication of Weber’s theory: when oscillations of electricity are set up in an unclosed circuit, Weber’s hypothetical electrical inertia should reveal itself in a retardation of the oscillations. Through the experiments that Helmholtz had suggested on the self-induction of doubly wound spirals, Hertz won the Philosophical Faculty prize"" he proved that the inertia of electricity is either zero or less than a very small value, thereby lending experimental support to Helmholtz’ theoretical judgment of the improbability of Weber’s theory.""(DSB).‎

‎First appearance of 4 famous and importent papers (2 of them in their final form) in which Hertz established by experiments the similarities between electric waves and light waves.""Hertz followed up his determination of the finite velocity of electric waves by performing a series of more qualitative experiments in 1888 on the analogy between electric and light waves. Passing electric waves through huge prisms of hard pitch, he showed that they refract exactly as light waves do. He polarized electric waves by directing them through a grating of parallel wires, and he diffracted them by interrupting them with a screen with a hole in it. He reflected them from the walls of the room, obtaining interference between the original and the reflected waves. He focused them with huge concave mirrors, casting electric shadows with conducting obstacles. The experiments with mirrors especially attracted attention, as they were the most direct disproof of action at a distance in electrodynamics. They and the experiments on the finite velocity of propagation brought about a rapid conversion of European physicists from the viewpoint of instantaneous action at a distance in electrodynamics to Maxwell’s view that electromagnetic processes take place in dielectrics and that an electromagnetic ether subsumes the functions of the older luminiferous ether.""
