Hermann Franz Moritz Kopp (30 October 1817 – 20 February 1892), German chemist, was born at Hanau, where his father, Johann Heinrich Kopp (1777–1858), a physician, was professor of chemistry, physics and natural history at the local lyceum.

[1] After attending the gymnasium of his native town, he studied at Marburg and Heidelberg, and then, attracted by the fame of Liebig, went in 1839 to Gießen, where he became a privatdozent in 1841, and professor of chemistry twelve years later.

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.

[1] Another question to which he gave much attention was the connection of the boiling point of compounds, organic ones in particular, with their composition.

"[2] In addition, Kopp wrote (1863) on theoretical and physical chemistry for the Graham-Otto Lehrbuch der Chemie, and for many years assisted Liebig in editing the Annalen der Chemie and the Jahresbericht.
