BORN, GUSTAV JACOB:
German histologist and medical author; born at Kempen, province of Posen, Prussia, April 22, 1851. He received his education first at the gymnasium of Görlitz, Prussian Silesia—where his father practised as a physician and held the position of Kreisphysicus (district physician)—and afterward at the universities of Breslau, Bonn, Strasburg, and Berlin, graduating as physician from Breslau in 1876. In the same year he was appointed assistant prosector and privat-docent at the University of Breslau, and in 1877 prosector. In 1886 he was elected assistant professor, and in 1898 professor of histology and comparative anatomy, at the same university, receiving the Prussian Order of the Red Eagle of the fourth class in the latter year.
Several technical inventions, as well as new methods in the field of microscopy and embryology, have made Born's name prominent. Well known among these is a method for reproducing and plasticallyenlarging small anatomical and embryological objects, which was described in "Zeitschrift für Wissenschaftliche Mikroscopie," vol. v.
Born has written about fifty essays and works pertaining to his specialty, among which are: "Ueber das Extremitätenskelett der Amphibien und Reptilien"; "Ueber die Nasenhöhle und den Thränennasengang bei Allen Wirbelthïeren von den Amphibien Aufwärts" (this series of articles is published in Gegenbauer's "Morphologisches Jahrbuch," vols. i.-vii.); "Beiträge zur Entwicklungsgeschichte des Säugethierherzens," in "Archiv für Mikroscopische Anatomie," vol. xxxii.; "Ueber die Derivate der Embryologischen Schlundbögen und Schlundspalten bei Säugethieren," ib. 1883; "Beiträge zur Bastardirung Zwischen den Einheimischen Ameisenarten," in Pflüger's "Archiv für die Gesammte Physiologie," 1883; "Biologische Untersuchungen," part 1: "Ueber den Einfluss der Schwere auf das Froschei," in "Archiv für Mikroscopische Anatomie," 1885; "Biologische Untersuchungen," part 2; "Weitere Beiträge zur Bastardirung Zwischen den Einheimischen Ameisen," ib. 1886; "Ueber Druckversuche an Froscheiern," in "Anatomischer Anzeiger," 1893, viii,. Nos. 18, 19. His most important work, however, is "Ueber Verwachsungs-Versuche mit Amphibienlarven," Leipsic, 1897.
