Hermann August Hagen
Hermann August Hagen (30 May 1817 – 9 November 1893) was a German entomologist who specialised in Neuroptera and Odonata. He had established himself as one of Europe's preeminent entomologists by 1867 when he accepted a position at Harvard University to curate the Museum of Comparative Zoology. In 1870 he became the first entomologist in the United States to hold the formal title, Professor of Entomology. Provided by Wikipedia
