After studying at Altona and Copenhagen, Fabricius went to Uppsala, Swed., to become a student of Carolus Linnaeus (Linnaeus, Carolus), who admired his work. Although famous for his entomological studies, Fabricius was appointed professor not only of natural history but also of economics and finance at the University of Kiel in 1775. His most important works include Systema Entomologiae (1775), Genera Insectorum (1776), Philosophia Entomologica (1778), Betrachtungen über die allgemeinen Einrichtungen in der Natur (1781; “Considerations upon the Universal Arrangements in Nature”), Species Insectorum (1781), Entomologia Systematica (1792–98), and Resultate natur-historischer Vorlesungen (1804; “Results of Natural History Lectures”).
