Für Aerzte und Philosophen besonders abgedruckt aus Wagners Handwörterbuch der Physiologie. - Braunschweig, Verlag von Friedrich Vieweg und Sohn, 1851, 8°, VIII, 143 pp., orig. gelbe Broschur. Diese sehr seltene Einzelausgabe wurde von Ernst Heinrich Weber (1795-1878) durch ein ausführliches achtseitiges Inhaltsverzeichnis erweitert. Mit Namenszug von Sigmund Exner auf Umschlag, die Randläsuren des Umschlags restauriert, die obere rechte Ecke mit geringfügigem Wasserschaden, unbeschnittenes und gutes Exemplar dieses sehr seltenen Klassikers der Physiologie. Ernst Heinrich Weber (1795-1878) was the German anatomist and physiologist who first introduced the concept of the just-noticeable difference, that is, the smallest difference perceivable between two similar stimuli. Weber was a professor at the University of Leipzig from 1818 until 1871. He is known chiefly for his work on sensory response to weight, temperature, and pressure; he described a number of his experiments in this area in De Tactu (1834;"Concerning Touch"). Weber determined that there was a threshold of sensation that must be passed before an increase in the intensity of any stimulus could be detected; the amount of increase necessary to create sensation was the just-noticeable difference. He further observed that the difference was a ratio of the total intensity of sensation, rather than an absolute figure; thus, a greater weight must be added to a 100-pound load than to a 10-pound load for a man carrying the load to notice the change. Similar observations were made on other senses, including sight and hearing. Weber also described a terminal threshold for all senses, the maximum stimulus beyond which no further sensation could be registered. Weber's findings were elaborated in Der Tastsinn und das Gemeingefühl (1851; "The Sense of Touch and the Common Sensibility"), which was considered to be "the foundation stone of experimental psychology." Weber's empirical observations were expressed mathematically by Gustav Theodor Fechner, who called his formulation Weber's law. -cf. denis Leri.

22,5 x 15 cm. Etat : Gut. 143 Seiten Halbleineneinband der Zeit, Ecken und Kanten etwas berieben. AUSSERORDENTLICHES EXEMPLAR AUS DEM BESITZ DES BERÜHMTEN PROF. DR. MAX RUPPERT FRANZ VON FREY: Durchschossenes Exemplar mit einigen handschriftlichen Bemerkungen von Frey und mit vielen losen handschriftlichen Aufzeichnungen von demselben. Sowie ein Brief der Chemischen Fabrik "Desitin" an denselben mit der Bitte um Expertise. Auf dem Vorsatz ein handschriftlicher Besitzeintrag H. Rein (Verwandter) und ebenfalls handschriftlich auf dem Vortitel ein Eintrag "M. v. Frey". ----------- Ernst Heinrich Weber (* 24. Juni 1795 in Wittenberg, Kurfürstentum Sachsen; 26. Januar 1878 in Leipzig, Königreich Sachsen) war ein deutscher Physiologe und Anatom. Weber beschäftigte sich mit der menschlichen, der vergleichenden und der mikroskopischen Anatomie sowie der Entwicklungsgeschichte der Tiere und der Physiologie, besonders deren physikalischer Seite; von ihm stammen bedeutende Untersuchungen zur Mechanik des Gehens sowie zum Druck-, Temperatur- und Ortssinn in der Haut des Menschen. Gemeinsam mit Gustav Theodor Fechner (18011887) gehört Weber zu den Begründern der experimentelle Psychologie und der Psychophysik. Auf ihn geht das Weber-Fechnersche Gesetz zurück. 1825 (und nochmals detaillierter 1834) beschrieb er den nach ihm benannten Weber-Versuch zur Prüfung einer Hörstörung. Er war der erste, der die Lateralisierung (einseitige Verstärkung der Schallwahrnehmung) unter bestimmten Umständen feststellte. Im Jahr 1845 berichteten Ernst und sein Eduard Weber über die verlangsamend auf die Herztätigkeit wirkende Vagusreizung. 1827 wurde er zum korrespondierenden Mitglied der Preußischen Akademie der Wissenschaften gewählt, 1859 wurde er auswärtiges Mitglied. In ihrem Gründungsjahr 1846 wurde er ordentliches Mitglied der Königlich Sächsischen Gesellschaft der Wissenschaften. Seit 1851 war er auswärtiges Mitglied der Göttinger Akademie der Wissenschaften[2] und seit 1863 der Bayerischen Akademie der Wissenschaften. 1858 wurde er zum Mitglied der Deutschen Akademie der Naturforscher Leopoldina gewählt.[3] Im Jahre 1859 wurde er in den Orden Pour le Mérite für Wissenschaften und Künste aufgenommen. Seit 1871 war Weber Ehrenbürger der Stadt Leipzig. Für seine Verdienste wurde Weber mit dem Komturkreuz des königlich-sächsischen Verdienstordens ausgezeichnet. Außerdem erhielt er den Titel eines Geheimen Medizinalrates. Am 23. Mai 2000 wurde der Asteroid (11042) Ernstweber nach ihm benannt. Quelle: Teilweise Wikipedia Auszug.
