## Life

After studying biology, Hartmut Greven received his doctorate in 1971 at the University of Münster with a thesis on faunistic-ecological and functional-morphological studies on native tardigrades, where he completed his post-doctoral habilitation in 1978 with a thesis entitled "Contributions to the reproductive biology of the genus Salamandra (Amphibia, Urodela)". After working at the Medical Faculty of the University of Münster and acting professorships at Paderborn and Düsseldorf, he became Professor of Zoomorphology at the former Institute for Zoomorphology, Cell Biology and Parasitology at the Heinrich Heine University Düsseldorf until his retirement.
Greven is co-editor of scientific journals (1988 to 2016 Acta Biologica Benrodis (ISBN 978-3-936616-83-5); since 1991 Zeitschrift für Fischkunde now Bulletin of Fish Biology (ISSN 1867-5417); since 2004 Entomologie heute (ISSN 1613-0448)). He is head of the Editorial Board of the German Society for Ichthyology, and he was president of that society until 2013. He has published numerous works on animal groups along with review articles and popular science essays.
