HERMANN FRANZ MORITZ KOPP (1817-1892), German chemist, was born on the 30th 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.
By the indirect method Kopp derived the following atomic volumes: C. 0.
He must not be confused with Emil Kopp (1817-1875), who, born at Warselnheim, Alsace, 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.
In addition to these and other laborious researches, Kopp was a prolific writer.
Theoretical considerations as to how far Kopp was justified in choosing the boiling-points under atmospheric pressure as being comparable states for different substances now claim our attention.
