Hermann Bonitz (29 July 1814 - 25 July 1888), German scholar, was born at Langensalza in Saxony.

Having studied at Leipzig under G Hermann and at Berlin under Böckh and Lachmann, he became successively teacher at the Blochmann Institute in Dresden (1836), Oberlehrer at the Friedrich-Wilhelms Gymnasium (1838) and the Graues Kloster (1840) in Berlin, professor at the gymnasium at Stettin (1842), professor at the university of Vienna (1849), member of the imperial academy (1854), member of the council of education (1864), and director of the Graues Kloster gymnasium (1867). He retired in 1888, and died in that year at Berlin.

He took great interest in higher education, and was chiefly responsible for the system of teaching and examination in use in the high schools of Prussia after 1882. But it is as a commentator on Plato and Aristotle that he is best known outside Germany. His most important works in this connection are:

• Disputationes Platonicae Duae (1837); Platonischie Studien (3rd ed., 1886)
• Observationes Crilicae in Aristotelis Libros Metaphysicos (1842)
• Observaliones Criticae in Aristotelis quae feruntur Magna Moralia et Ethica Eudemia (1844)
• Alexandri Aphrodisiensis Commentarius in Libros Metaphysicos Aristotelis (1847)
• Aristotelis Metaphysica (1848-1849)
• Über die Kalegorien des A. (1853)
• Aristotelische Studien (1862-1867)
• Index Aristoklicus (1870)

Other works:

• Uber den Ursprung der hosnerischen Gedichte (5th ed., 188,)
• Beiträge zur Erklarung des Thukydides (1854), des Sophokles (1856-1857)

He also wrote largely on classical and educational subjects, mainly for the Zeitschrift fur die osterreichischen Gymnasien .

A full list of his writings is given in the obituary notice by Theodor Gomperz in the Biographisches Jahrbuch fr Altertumskunde (1890).
