1911 Encyclopædia Britannica/Erdmann, Otto Linné

ERDMANN, OTTO LINNÉ (1804–1869), German chemist, son of Karl Gottfried Erdmann (1774–1835), the physician who introduced vaccination into Saxony, was born at Dresden on the 11th of April 1804. In 1820 he began to attend the medico-chirurgical academy of his native place, and in 1822 he entered the university of Leipzig where in 1827 he became extraordinary professor, and in 1830 ordinary professor of chemistry. This office he held until his death, which happened at Leipzig on the 9th of October 1869. He was particularly successful as a teacher, and the laboratory established at Leipzig under his direction in 1843 was long regarded as a model institution. As an investigator he is best known for his work on nickel and indigo and other dye-stuffs. With R. F. Marchand (1813–1850) he also carried out a number of determinations of atomic weights. In 1828, in conjunction with A. F. G. Werther (1815–1869), he founded the Journal für technische und ökonomische Chemie, which became in 1834 the Journal für praktische Chemie. He was also the author of Über das Nickel (1827), Lehrbuch der Chemie (1828), Grundriss der Waarenkunde (1833), and Über das Studium der Chemie (1861).
