First printing of Helmholtz's own report on the meeting of the 23rd of July 1847 in the Physical Society of Berlin. In the meeting he presented with great success his groundbreaking paper ""Ueber die Erhaltung der Kraft"". In the paper printed in the ""Fortschritte"", Helmholtz summarizes the main mathematical and historical features of his Conservation of Energy-principle as it was laid down in ""Ueber die Erhaltung der Kraft"".""On July 21 he (Helmholtz) announced to du Bois-Reymond that he would bring forward his 'Conservation of Energy' on the 23rd at the Physical Society. The meeting was one of the most memorable in the annals of the Society"" as du Bois tells us, Helmholtz revealed himself at one bound, to the surprise of all his friends, as a master of mathematical physics. The members of the Physical Society were acquainted with the Law of the Conservation of Energy when it was still unknown to all the rest of the world.""(Leo Koenigsberger in ""Hermann von Helmholtz"", pp. 38).In his groundbreking work Helmholtz announced the first comprehensive statement of the first law of thermodynamics: All modes of energy, heat, light, electricity, and all chemical phenomena, are capable of transformation from one to the other but are indestructible and cannot be created. Helmholtz offered his paper to Poggendorf's 'Annalen', but the editor declined to publish so dangerous a speculation. Helmholtz had it printed at his own expense in a small number in 1847.

First printing of the 3 main papers in the famous Helmholtz-Clausius controversy about the principle of the ""Conservation of Energy"". His reply to Clausius contains very importent additons to his conservation law, as it clarifies his use of the concepts of ""energy"", ""vis viva"", ""electrical tension"" , ""potentials"" etc.Helmholtz famous work Über die Erhaltung der Kraft"" from 1847 gave the first comprehensive statement of the first law of thermodynamics: All modes of energy, heat, light, electricity, and all chemical phenomena, are capable of transformation from one to the other but are indestructible and cannot be created. Clausius (in the papers offere) critized helmholtz on his theory of heat over the consistency of the physical interpretation and of the use mathematics. He argued that Helmholtz's demonstration of his conservation law was valid only for Helmholtz's particulat model of matter, and that he had not understood the notion of the potential. This criticism lead Helmholtz expand and clarify the central concepts of physics, importent steps in the history of theoretical physics.

First apperance - in full - of this importent paper in which for the first time the 2 laws of thermodynamics were applied to electrical phenomena. Parts of the paper were published already in 1877.""In 1877 Helmholtz attempted to predict theoretically the electromotive force of a galvanic cell for different concentrations of a salt solution. Under certain conditions the cell can be treated as a reversible cycle and the laws of Carnot and Clapeyron applied to it. The theory was in substantial agreement with experimental data by James Moser.""(DSB). - The Moser-paper confirming Helmholtz theory is printed here on pp. 216-219, taken from Monatsberichte der Berl. Akad., 1877.""In his work 'On Galvanic Currents', Helmholtz was the first to apply the two laws of thermodynamics to electricity. In order to keep up a current of electricity through any conductor it is necessary to expend a certain amount of chemical or mechanical work"" the supply of positive electricity in the positive end of the conductor must be perpetually renewed, in order to oppose the repulsive force of the positive electricity there accumulated, and the same holds for the negative electricity at the negative end.""(Koenigsberger ""Hermann von helmholtz"", pp. 309-12).

First appearance of this milestone paper which represents the first, and most importent, step towards his great work laid down in ""Über die Erhaltung der Kraft"", 1847. This is Helmholtz' FIRST PAPER ON THE CONSERVATION OF FORCE""At the beginning of October, 1846, Helnmholtz sent a 'Report on Work done on the Theory of Animal Heat for 1845', at du Bois' request, to the ""Fortschritte der Physik"", issued by the Physical Society. (the paper offered). This was merely an abstract from the article in the Encyclopaedic Dictionary.....BUT IT ANTICIPATES MORE DEFINITELY THE CONDCLUSIONS OF HIS GREAT WORK. He states without hesitation that the material theory of heat is no longer tenable, and that a kinetic theory must be substituted for it, since heat originates in mechanical forces, either directly by friction, or indirectly from an electrical current produced by themotion of magnets. This conception of heat as a motion involves the conclusion that mechanical, electrical and chemical forces must always be the definite equivalent of one and the same energy, whatever the mode by which one force is transformed into another. The empirical confirmation of this law must be the imperative duty of physicists and physiologists.""(Leo Koenigsberger in ""Hermann von Helmholtz"", pp. 34-35).""In the ""Fortschritte der Physik"" for 1845, which appeared in 1847, Helmholtz published a report on theories of physiological heat which he later acknowledged as belonging to his work on the conversation of force.""(Jungnickel & McCormach ""Intellectual Masteryof Nature, Vol. 1, p. 157).

First appearance of this founding paper in the modern theory of colour, in which Helmholtz proved the surprising fact that there are only two among the colours of the spectrum, yellow and indigo-blue, which together yields pure white, that is, are complementary to each other, whereas their combination had always been supposed to produce green.""Helmholtz turned to the intricate problems of color vision in 1852 with an attack on Sir David Brewster's new theory of light. Brewster had maintained the objective reality of three primary colors by supposing, in opposition to Newton, that there exist three distinct kinds of light, each of which excites in the eye one of the sensations red, yellow, or blue. Helmholtz regarded the theory as still another confusion of physical stimulus and subjective responce....He also revived Young's theory of color visoin...only to refute it. He had discovered that spectral colors, when mixed, always yield a duller color of less-than-spectral saturation. Therefore the whole idea that all colors may be obtained from mixtures of three primary colors must be incorrect, he concluded, for the spectral colorss, at least, can never be obtained in their full saturation by mixing any three of their number....Although Helmholtz dismissed Young's theory in 1852, by 1858 he had changed his mind and become its formost advocate. In order to save Ypoung's theory....Helmholtz asumed that Young's physiological primaries are not spectral colors att all, but colors of far greater-than-spectral saturation...""(DSB VI, pp. 246-247).

First appearance (also in Berichte königl. Preuss. Ak. the same year) of these short notes in which Helmholtz announced his discovery and measurements of the time delay of nervous impulses, a discovery ""which opened a new and unbounded field of investigations to physiologists"". It is one the most importent discoveries in physiology in the 19th century.""Du Bois-Reymond... received Helmholtz's first two-page note. Müller, to whom Du Bois tried to ecplain it, insisted on rejecting the conclusion, arguing that Helmholtz had not eliminated the time for the contraction of the muscle. Humboldt, du Bois wrote Helmholtz, ""war ganz depaysiert"", and at first refused to send the paper to Paris for publication there. Du Bois had first to edit it and then Humboldt, won over, had it published in the ""Comptes Rendus"", adding a further explanatory foot-note of his own. By summer, Müller had also been won, and then helmholtz published his longer paper in which he included a measurement of tghe time of the muscular cobntraction and nes determinations of the rate of transmission.""(Boring ""History of Experimental Psychology"", p. 48).""To separate the movement in time from the event of will that caused it was in a sense to separate the body from the mind, and almost from the personality or self. At any rate, helmholtz's discovery was a step in the analysis of bodily motionthat changed it from an instantaneous occurrence to a temporal series of events, and it thus contributed to the materialistic view of the psychophysical organuismthat was the essence of nineteenthy century science.... The most impiortent effect of the experiment and all the research that followed upon it was, however, thatit brought the soul to time, as it were, measured what had been ineffable, actually captured the essential agent of mind in the toils of natural science."" (Boring ""History of Experimental Psychology"", p. 42).""Helmholtz’ research in sensory physiology began in 1850, when he determined the velocity of the nerve impulse in the sciatic nerve of the frog. In 1852 he obtained more precise results through his invention of the myograph. This device, in which the muscle traces the motion of its contraction upon a rotating drum, permitted more exact measurement of the small time intervals involved than any previous method. Helmholtz’ measurements yielded not only a finite velocity for nerve propagation but also the surprisingly slow one of about ninety feet per second. The result was considered a victory for the mechanistic school, for it seemed to confirm du Bois-Reymond’s hypothesis that the nerve impulse consisted in the progressive rearrangement of ponderable molecules.""(DSB).
Paris, Victor Masson, 1869, in-8, III-137 pages, Broché, couvertures d'origine, Première édition française de cet important traité. Par "force", Helmholtz, qui titrait ce traité originellement publié en allemand en 1847 "Über die Erhaltung der Kraft", entend "énergie". Jeune physiologiste alors peu connu, Hermann von Helmholtz (1821-1894) fait émerger ici le principe de conservation de l'énergie, à la fois sur des bases philosophiques et physiques, et il met en évidence deux principes nouveaux : la force vive et la force de tension, ébauches de l'énergie cinétique et de l'énergie potentielle. "It drew heavily on the works of Sadi Carnot, Clapeyron, Holzmann, and Joule, although it was far more comprehensive than those previous treatise". Helmholz exerça une influence considérable sur la pensée scientifique du XIXe siècle, non seulement pour le succès de ses travaux, menés dans les domaines les plus variés (énergie, optique, épistémologie, électrodynamique...), mais aussi pour ses qualités de professeur et de pédagogue, qui tenta de rendre ses connaissances accessibles au plus grand nombre avec ses "conférences populaires" ("Populare wissenschaftlische Voträge").
