Hermann Loew

Friedrich Hermann Loew (19 July 1807 – 21 April 1879) was a German entomologist who specialised in the study of Diptera, an order of insects including flies, mosquitoes, gnats and midges. He described many world species and was the first specialist to work on the Diptera of the United States.

Hermann Loew was born in Weissenfels, Saxony a short distance south of Halle (Germany). The Loew family, though not wealthy, was well-placed. Loew's father was a functionary for the Department of Justice of the Duchy of Saxony who later became a Geheimer Regierungsrath of Prussia. Between 1817 and 1829 Loew attended first the Convent school of Rossleben, then the University of Halle-Wittenberg, graduating in mathematics, philology and natural history.

Recognizing his abilities as a mathematician, the university, on his graduation, appointed him as a lecturer in the same subjects. In 1830 he went to Berlin and gave lessons in different higher grade schools including the Kadetten-Schule military school. Here he was private tutor to Prince Biron heir to the Duchy of Courland and Semigallia and the young Friedrich Wilhelm Ernst Albrecht von Graefe (1828–1870) later one of the most famous oculists of all times. In 1834 Loew was appointed superior teacher (Oberlehrer) at the Friedrich-Wilhelm-Gymnasium in Posen, known today as St. John Cantius High School in Poznań, Poland where he taught mathematics and natural history. In the same year he married the daughter of senior preacher Ehricht, a favourite sermoniser. Several of Loew's pupils at Posen became scientific celebrities, the most notable being the philosopher Kuno Fischer (1824–1907) and the mathematicians Leo Königsberger (1837–1921) and Lazarus Immanuel Fuchs (1835–1902). That they became such, gifted though they were, must have been due to Loew's extraordinary abilities and his popularity with students.
