Hermann Köchly (born Leipzig, 5 August 1815; died Trieste, 3 December 1876) was a German philologist and educational reformer.
He studied at Leipzig, taught at the Saalfeld Progymnasium (1837) and at the Dresden Kreuzschule (1840). In February 1849, Köchly was elected to the lower house of the Kingdom of Saxony, but that same year was forced to flee to Brussels on account of his participation in the May insurrection. He was appointed professor of classical philology at Zürich in 1851, and at Heidelberg in 1864. He was a member of the Reichstag from 1871 to 1873 and attached himself to the Progressive Party.
The scheme set forth in these pamphlets stressed the natural sciences, and, in Latin and Greek, urged emphasis on content rather than on grammar and style, and the gradual abolishment of speaking and writing those languages. The plan was adopted in Saxony almost immediately.
He did translations, especially of Caesar, Aeschylus, etc. A collection of his smaller works is found in his Opuscula academica (Leipzig, 1853–56), Akademische Vorträge und Reden (Zürich, 1856) and Opuscula philologica (Leipzig 1881-82).
