KOPP, HERMANN FRANZ MORITZ (1817-1892) , German chemist, was born on the 3oth of October 1817 at Hanau, where his father, Johann Heinrich Kopp (1777-1858), a physician, was professor of

chemistry

, physics and natural history at the Lyceum.
After attending the gymnasium of his native town, he studied at Marburg and

Heidelberg

HEIDELBERG

, and then, attracted by the fame of

Liebig

LIEBIG, JUSTUS VON, BARON (1803-1873)

, went in 1839 to Giessen, where he became a privatdozent in 1841, and professor of

chemistry

twelve years later. In 1864 he was called to

Heidelberg

HEIDELBERG

in the same capacity, and he remained there till his death on the loth of February 1892. Kopp devoted himself especially to physico-chemical inquiries, and in the history of chemical theory his name is associated with several of the most important correlations of the physical properties of substances with their chemical constitution. Much of his

work

was concerned with specific volumes, the conception of which he set forth in a

paper

published when he was only twenty-two years of age; and the principles he established have formed the basis of subsequent investigations in that subject, although his results have in some cases undergone modification. Another question to which he gave much attention was the connexion of the boiling-point of compounds, organic ones in particular, with their composition. In addition to these and other laborious researches, Kopp was a prolific writer. In 1843-184.7 he published a comprehensive History of Chemistry, in four volumes, to which three supplements were added in 1869-1875. The Development of Chemistry in

Times appeared in 1871-1874, and in 1886 he published a

in two volumes on Alchemy in Ancient and Modern Times. In addition he wrote (1863) on theoretical and physical chemistry for the Graham-Otto Lehrbuch der Chemie, and for many years assisted

Liebig

LIEBIG, JUSTUS VON, BARON (1803-1873)

in editing the Annalen der Chemie and the Jahresbericht.
He must not be confused with Emil. KoPP (1817-1875), who, born at Warselnheim,

Alsace

ALSACE (Ger. Elsass)

, became in 1847 professor of

toxicology

and chemistry at the Ecole superieure de Pharmacie at Strasburg, in 1849 professor of physics and chemistry at Lausanne, in 1852 chemist to a Turkey-red factory near Manchester, in 1868 professor of technology at Turin, and finally, in 1871, professor of technical chemistry at the

Polytechnic

of Zurich, where he died in 1875.
