German physicist; born Nov. 12, 1856, in Berlin. He was only twenty years old when he graduated from the university of his native city, and received the degree of Ph.D. upon the presentation of an excellent thesis, "Untersuchungen über die Natur des Vokalklanges," which appeared in Poggendorff's "Annalen der Physik und Chemie" for 1876. Continuing his studies at the University of Berlin until 1879, he was in that year appointed assistant in the Physical Institute of the University of Breslau. In 1890 Auerbach was appointed assistant professor of physics in Jena University, which position he continues to occupy.
Among Auerbach's scientific contributions is a treatise on hydrodynamics, "Die Theoretische Hydrodynamik. Nach dem Gange der Entwickelungen in der Neuesten Zeit in Kürze Dargestellt," Brunswick, 1881, which received the prize of the Reale Istituto Veneto di Scienze, Lettere ed Arti, and was subsequently translated into Italian (Milan, 1882). Auerbach is also the author of numerous papers of a more technical nature in the "Archiv für Physiologie," in Poggendorff's "Annalen der Physik und Chemie," in the "Nachrichten der Königlichen Gesellschaft der Wissenschaften und der Georg-August Universität zu Göttingen," etc. Short notices of his scientific contributions may be found in the annual "Die Fortschritte der Physik," G. Reimer, Berlin.
